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.
وَحَدَّثَنِي نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا بِشْرٌ، - يَعْنِي ابْنَ مُفَضَّلٍ - عَنْ خَالِدٍ، عَنْ أَنَسِ بْنِ سِيرِينَ، قَالَ سَمِعْتُ جُنْدَبَ بْنَ عَبْدِ اللَّهِ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ مَنْ صَلَّى الصُّبْحَ فَهُوَ فِي ذِمَّةِ اللَّهِ فَلاَ يَطْلُبَنَّكُمُ اللَّهُ مِنْ ذِمَّتِهِ بِشَىْءٍ فَيُدْرِكَهُ فَيَكُبَّهُ فِي نَارِ جَهَنَّمَ ‏"‏ ‏.‏
