He who observed two prayers at two cool (hours) would enter Paradise.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ صَلَّى الْبَرْدَيْنِ دَخَلَ الْجَنَّةَ  

"I heard the Messenger of Allah ﷺ say: 'No one will enter the Fire who prays before the sun rises and before it sets.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ يَلِجُ النَّارَ أَحَدٌ صَلَّى قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ أَنْ تَغْرُبَ  

"I heard the Messenger of Allah ﷺ say: 'He will never enter the Fire, the one who prays before the sun rises and before it sets.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَنْ يَلِجَ النَّارَ مَنْ صَلَّى قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا  

He who prayed the morning prayer (in congregation) he is in fact under the protection of Allah. And it can never happen that Allah should demand anything from you in connection with the protection (that He guarantees) and one should not get it. He would then throw him in the fire of Hell.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ صَلَّى الصُّبْحَ فَهُوَ فِي ذِمَّةِ اللَّهِ فَلاَ يَطْلُبَنَّكُمُ اللَّهُ مِنْ ذِمَّتِهِ بِشَىْءٍ فَيُدْرِكَهُ فَيَكُبَّهُ فِي نَارِ جَهَنَّمَ  

I heard Jundab b. Qasri saying that the Messenger of Allah ﷺ said: He who observed the morning prayer (in congregation), he is in fact under the protection of Allah and it never happens that Allah should make a demand in connection with the protection (that He guarantees and should not get it) for when he asks for anything in relation to His protection, he definitely secures it. He then throws him flatly in the Hell-fire.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ صَلَّى صَلاَةَ الصُّبْحِ فَهْوَ فِي ذِمَّةِ اللَّهِ فَلاَ يَطْلُبَنَّكُمُ اللَّهُ مِنْ ذِمَّتِهِ بِشَىْءٍ فَإِنَّهُ مَنْ يَطْلُبْهُ مِنْ ذِمَّتِهِ بِشَىْءٍ يُدْرِكْهُ ثُمَّ يَكُبَّهُ عَلَى وَجْهِهِ فِي نَارِ جَهَنَّمَ  

Messenger of Allah ﷺ said, "Angels come to you in succession by night and day and all of them get together at the time of the Fajr and ʿAsr prayers. Those who have passed the night with you (or stayed with you) ascend (to the Heaven) and Allah asks them, though He knows everything about you, well, "In what state did you leave my slaves?" The angels reply: "When we left them they were praying and when we reached them, they were praying."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَتَعَاقَبُونَ فِيكُمْ مَلاَئِكَةٌ بِاللَّيْلِ وَمَلاَئِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِي صَلاَةِ الْفَجْرِ وَصَلاَةِ الْعَصْرِ ثُمَّ يَعْرُجُ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ وَهْوَ أَعْلَمُ بِهِمْ كَيْفَ تَرَكْتُمْ عِبَادِي فَيَقُولُونَ تَرَكْنَاهُمْ وَهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ وَهُمْ يُصَلُّونَ  

The Prophet ﷺ said, "Angels keep on descending from and ascending to the Heaven in turn, some at night and some by daytime, and all of them assemble together at the time of the Fajr and ʿAsr prayers. Then those who have stayed with you over-night, ascent unto Allah Who asks them, and He knows the answer better than they, "How have you left My slaves?" They reply, "We have left them praying as we found them praying." If anyone of you says "Amin" (during the Prayer at the end of the recitation of Surat-al-Faitiha), and the angels in Heaven say the same, and the two sayings coincide, all his past sins will be forgiven."  

قَالَ النَّبِيُّ ﷺ الْمَلاَئِكَةُ يَتَعَاقَبُونَ مَلاَئِكَةٌ بِاللَّيْلِ وَمَلاَئِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِي صَلاَةِ الْفَجْرِ وَالْعَصْرِ ثُمَّ يَعْرُجُ إِلَيْهِ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ وَهْوَ أَعْلَمُ فَيَقُولُ كَيْفَ تَرَكْتُمْ {عِبَادِي} فَيَقُولُونَ تَرَكْنَاهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ يُصَلُّونَ  

Messenger of Allah ﷺ said, "(A group of) angels stay with you at night and (another group of) angels by daytime, and both groups gather at the time of the 'Asr and Fajr prayers. Then those angels who have stayed with you overnight, ascend (to Heaven) and Allah asks them (about you) ---- and He knows everything about you. "In what state did you leave My slaves?' The angels reply, 'When we left them, they were praying, and when we reached them they were praying.' "  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَتَعَاقَبُونَ فِيكُمْ مَلاَئِكَةٌ بِاللَّيْلِ وَمَلاَئِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِي صَلاَةِ الْعَصْرِ وَصَلاَةِ الْفَجْرِ ثُمَّ يَعْرُجُ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ وَهْوَ أَعْلَمُ بِكُمْ فَيَقُولُ كَيْفَ تَرَكْتُمْ عِبَادِي فَيَقُولُونَ تَرَكْنَاهُمْ وَهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ وَهُمْ يُصَلُّونَ  

Messenger of Allah ﷺ said, "There are angels coming to you in succession at night, and others during the day, and they all gather at the time of ʿAsr and Fajr prayers. Then the angels who have stayed with you overnight ascend (to the heaven) and He (Allah) asks them though He perfectly knows their affairs. 'In what state have you left my slaves?' They say, 'When we left them, they were praying and when we came to them they were praying.' "  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَتَعَاقَبُونَ فِيكُمْ مَلاَئِكَةٌ بِاللَّيْلِ وَمَلاَئِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِي صَلاَةِ الْعَصْرِ وَصَلاَةِ الْفَجْرِ ثُمَّ يَعْرُجُ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ وَهْوَ أَعْلَمُ كَيْفَ تَرَكْتُمْ عِبَادِي فَيَقُولُونَ تَرَكْنَاهُمْ وَهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ وَهُمْ يُصَلُّونَ  

Jarir said, "We were with the Prophet ﷺ and he looked at the moon--full-moon--and said, 'Certainly you will see your Lord as you see this moon and you will have no trouble in seeing Him. So if you can avoid missing (through sleep or business, etc.) a prayer before the sunrise (Fajr) and a prayer before sunset (ʿAsr), you must do so.' He then recited Allah's Statement: And celebrate the praises Of your Lord before the rising of the sun and before (its) setting." (50.39) Ismaʿil said, "Offer those prayers and do not miss them."  

كُنَّا عِنْدَ النَّبِيِّ ﷺ فَنَظَرَ إِلَى الْقَمَرِ لَيْلَةً يَعْنِي الْبَدْرَ فَقَالَ إِنَّكُمْ سَتَرَوْنَ رَبَّكُمْ كَمَا تَرَوْنَ هَذَا الْقَمَرَ لاَ تُضَامُّونَ فِي رُؤْيَتِهِ فَإِنِ اسْتَطَعْتُمْ أَنْ لاَ تُغْلَبُوا عَلَى صَلاَةٍ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا فَافْعَلُوا ثُمَّ قَرَأَ {وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ الْغُرُوبِ} قَالَ إِسْمَاعِيلُ افْعَلُوا لاَ تَفُوتَنَّكُمْ  

We were with the Prophet ﷺ on a full moon night. He looked at the moon and said, "You will certainly see your Lord as you see this moon, and there will be no trouble in seeing Him. So if you can avoid missing (through sleep, business, etc.) a prayer before the rising of the sun (Fajr) and before its setting (ʿAsr) you must do so. He (the Prophet ﷺ ) then recited the following verse: And celebrate the praises Of Your Lord before The rising of the sun And before (its) setting." (50.39)  

لِي جَرِيرُ بْنُ عَبْدِ اللَّهِ كُنَّا عِنْدَ النَّبِيِّ ﷺ إِذْ نَظَرَ إِلَى الْقَمَرِ لَيْلَةَ الْبَدْرِ فَقَالَ أَمَا إِنَّكُمْ سَتَرَوْنَ رَبَّكُمْ كَمَا تَرَوْنَ هَذَا لاَ تُضَامُّونَ أَوْ لاَ تُضَاهُونَ فِي رُؤْيَتِهِ فَإِنِ اسْتَطَعْتُمْ أَنْ لاَ تُغْلَبُوا عَلَى صَلاَةٍ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا فَافْعَلُوا ثُمَّ قَالَ فَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا  

We were in the company of the Prophet ﷺ on a fourteenth night (of the lunar month), and he looked at the (full) moon and said, "You will see your Lord as you see this moon, and you will have no trouble in looking at Him. So, whoever can, should not miss the offering of prayers before sunrise (Fajr prayer) and before sunset (ʿAsr prayer)." Then the Prophet ﷺ recited: 'And celebrate the praises of your Lord before the rising of the sun and before (its) setting.' (50.39)  

كُنَّا جُلُوسًا لَيْلَةً مَعَ النَّبِيِّ ﷺ فَنَظَرَ إِلَى الْقَمَرِ لَيْلَةَ أَرْبَعَ عَشْرَةَ فَقَالَ إِنَّكُمْ سَتَرَوْنَ رَبَّكُمْ كَمَا تَرَوْنَ هَذَا لاَ تُضَامُونَ فِي رُؤْيَتِهِ فَإِنِ اسْتَطَعْتُمْ أَنْ لاَ تُغْلَبُوا عَلَى صَلاَةٍ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا فَافْعَلُوا ثُمَّ قَرَأَ {وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ الْغُرُوبِ}  

We were sitting with the Prophet ﷺ and he looked at the moon on the night of the full-moon and said, "You people will see your Lord as you see this full moon, and you will have no trouble in seeing Him, so if you can avoid missing (through sleep or business, etc.) a prayer before sunrise (Fajr) and a prayer before sunset (ʿAsr) you must do so." (See Hadith No. 529, Vol. 1)  

كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ ﷺ إِذْ نَظَرَ إِلَى الْقَمَرِ لَيْلَةَ الْبَدْرِ قَالَ إِنَّكُمْ سَتَرَوْنَ رَبَّكُمْ كَمَا تَرَوْنَ هَذَا الْقَمَرَ لاَ تُضَامُّونَ فِي رُؤْيَتِهِ فَإِنِ اسْتَطَعْتُمْ أَنْ لاَ تُغْلَبُوا عَلَى صَلاَةٍ قَبْلَ طُلُوعِ الشَّمْسِ وَصَلاَةٍ قَبْلَ غُرُوبِ الشَّمْسِ فَافْعَلُوا
