I am the one who is best informed of the time of this prayer, i.e. the night prayer. The Messenger of Allah ﷺ used to offer it at the hour when the moon went down on its third night. (Using translation from Abū Dāʾūd 419)  

«إِنِّي لَأَعْلَمُ النَّاسِ بِوَقْتِ هَذِهِ الصَّلَاةِ صَلَاةِ الْعِشَاءِ الْآخِرَةِ كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّيهَا لِسُقُوطِ الْقَمَرِ لِثَالِثَةٍ»  

I would offer my noon prayer with the Messenger of Allah ﷺ and took a handful of gravels so that they might become cold in my hand and I placed them (before me) so that I may put my forehead on them at the time when I would prostrate. I did this due to the intensity of heat. (Using translation from Abū Dāʾūd 399)  

«كُنْتُ أُصَلِّي الظُّهْرَ مَعَ رَسُولِ اللَّهِ ﷺ فَآخُذُ قَبْضَةً مِنَ الْحَصَى لِيَبْرُدَ فِي كَفِّي أَضَعُهَا لِجَبْهَتِي أَسْجُدُ عَلَيْهَا لِشِدَّةِ الْحَرِّ»  

[Machine] The Messenger of Allah ﷺ said, "Shall I not inform you about the prayer of the hypocrite? It is when he delays the Asr (afternoon) prayer until the sun becomes like the hump of a camel." This hadith was narrated by Muslim from the narration of Al-Ala' bin Abdul Rahman from Anas from the Prophet ﷺ who said, "This is the prayer of the hypocrite: he sits until the sun turns yellow."  

قَالَ رَسُولُ اللَّهِ ﷺ «أَلَا أُخْبِرُكُمْ بِصَلَاةِ الْمُنَافِقِ أَنْ يُؤَخِّرَ الْعَصْرَ حَتَّى كَانَتِ الشَّمْسُ كَثَرْبِ الْبَقَرَةِ صَلَّاهَا» أَخْرَجَ مُسْلِمٌ حَدِيثَ الْعَلَاءِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَنَسٍ عَنِ النَّبِيِّ ﷺ قَالَ «تِلْكَ صَلَاةُ الْمُنَافِقِ يَجْلِسُ أَحَدُهُمْ حَتَّى إِذَا اصْفَرَّتِ الشَّمْسُ» الْحَدِيثَ  

[Machine] "The farthest two men in companionship of the Messenger of Allah ﷺ were Abu Lubabah ibn Abd al-Mundhir and his family in Quba, and Abu Abs ibn Jabr with his residence in Bani Harithah. They used to pray the Asr prayer with the Messenger of Allah ﷺ , and then they would go to their people who had not yet prayed, in order to hasten the Messenger of Allah ﷺ with them."  

«كَانَ أَبْعَدُ رَجُلَيْنِ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ دَارًا أَبُو لُبَابَةَ بْنِ عَبْدِ الْمُنْذِرِ وَأَهْلُهُ بِقُبَاءَ وَأَبُو عَبْسِ بْنِ جَبْرٍ وَمَسْكَنُهُ فِي بَنِي حَارِثَةَ فَكَانَا يُصَلِّيَانِ مَعَ رَسُولِ اللَّهِ ﷺ الْعَصْرَ ثُمَّ يَأْتِيَانِ قَوْمَهُمَا وَمَا صَلَّوْا لِتَعْجِيلِ رَسُولِ اللَّهِ ﷺ بِهَا»  

[Machine] That the angel Gabriel came to the Prophet ﷺ to teach him the prayer, and he recited it word for word, like the hadith of Wahb bin Kaysan, equally for both "and as for the second witness." Authentic and well-known.  

أَنَّ جِبْرِيلَ أَتَى النَّبِيَّ ﷺ يُعَلِّمُهُ الصَّلَاةَ فَسَاقَ الْمَتْنَ بِمِثْلِ حَدِيثِ وَهْبِ بْنِ كَيْسَانَ سَوَاءً «وَأَمَّا الشَّاهِدُ الثَّانِي» صحيح مشهور  

[Machine] The Prophet ﷺ said, "Gabriel visited me in Mecca twice." Then he mentioned the hadith in a similar manner, "Abdul Kareem, this is the son of Abu Al-Mukhariq, without a doubt, and I have only brought him as a witness." Abdul Kareem is present.  

قَالَ النَّبِيُّ ﷺ «أَمَّنِي جِبْرِيلُ بِمَكَّةَ مَرَّتَيْنِ» فَذَكَرَ الْحَدِيثَ بِنَحْوِهِ «عَبْدُ الْكَرِيمِ هَذَا هُوَ ابْنُ أَبِي الْمُخَارِقِ بِلَا شَكٍّ وَإِنَّمَا خَرَّجْتُهُ شَاهِدًا» عبد الكريم واه  

[Machine] That Jibril came to the Prophet ﷺ and prayed the prayers with him twice, except for the Maghrib prayer.  

«أَنَّ جِبْرِيلَ أَتَى النَّبِيَّ ﷺ فَصَلَّى بِهِ الصَّلَوَاتِ وَقْتَيْنِ إِلَّا الْمَغْرِبَ»
