IMPORTANCE OF THE DAWN PRAYER H 390 "Whosoever prays the dawn prayer is guaranteed the safety of Allah. So do not bother him (except in truth) because, if Allah takes any of you being guilty of breaching His safety He reaches for him and that person is hurled into the Fire on his face." R 390 Muslim with a chain up to Jundab, the son of Abdullah who related that the Prophet, praise and peace be upon him, said this.
389- وعن جندب بن عبد الله رضي الله عنه ، قَالَ : قَالَ رَسُول الله صلى الله عليه وآله وسلم : "مَنْ صَلَّى صَلاةَ الصُّبْحِ ، فَهُوَ في ذِمَّةِ الله ، فَلاَ يَطْلُبَنَّكُمُ الله مِنْ ذِمَّتِهِ بِشَيْءٍ ، فَإنَّهُ مَنْ يَطْلُبُهُ مِنْ ذِمَّتِهِ بِشَيْءٍ يُدْرِكْهُ ، ثُمَّ يَكُبُّهُ عَلَى وَجْهِهِ في نَارِ جَهَنَّمَ" رواه مسلم .
