'Uthman b. 'Affan (narrated the mosque after evening prayer and sat alone. I also sat alone with him, so he said: 0, son of my brother, I heard the Messenger of Allah ﷺ say: He who observed the 'Isha' prayer in congregation, it was as if he prayed up to midnight, and he who prayed the morning prayer in congregation, it was as if he prayed the whole night.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ فَكَأَنَّمَا قَامَ نِصْفَ اللَّيْلِ وَمَنْ صَلَّى الصُّبْحَ فِي جَمَاعَةٍ فَكَأَنَّمَا صَلَّى اللَّيْلَ كُلَّهُ  

This hadith has been narrated by the chain of transmitters by Abu Sahl 'Uthman b. Hakim.  

عَنْ أَبِي سَهْلٍ عُثْمَانَ بْنِ حَكِيمٍ بِهَذَا الإِسْنَادِ مِثْلَهُ  

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  

" He would throw him in fire."  

عَنِ النَّبِيِّ ﷺ بِهَذَا وَلَمْ يَذْكُرْ فَيَكُبَّهُ فِي نَارِ جَهَنَّمَ
