حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا أَشْعَثُ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ بْنِ جُنْدَبٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ مَنْ صَلَّى الصُّبْحَ فَهُوَ فِي ذِمَّةِ اللَّهِ عَزَّ وَجَلَّ "
It was narrated from Samurah bin Jundab that the Prophet (ﷺ) said:
"Whoever offers the morning prayer, he is under the protection of Allah, the Mighty and Sublime."
