Sahih Muslim , Book 5, Hadith 330 (In-Book) ⓘ

Anas b. Sirin reported: I heard Jundab b. Qasri saying that the Messenger of Allah 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.

وَحَدَّثَنِيهِ يَعْقُوبُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ خَالِدٍ، عَنْ أَنَسِ بْنِ سِيرِينَ، قَالَ سَمِعْتُ جُنْدَبًا الْقَسْرِيَّ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ 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 ‏" ‏ ‏.‏
