Jami` at-Tirmidhi, Book 36, Hadith 57 (In-Book) ⓘ
Ibn 'Abbas said: " The Messenger of Allah (s.a.w) would spend many consecutive nights and his family did not have supper, and most of the time their bread was barley bread."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُعَاوِيَةَ الْجُمَحِيُّ، حَدَّثَنَا ثَابِتُ بْنُ يَزِيدَ، عَنْ هِلاَلِ بْنِ خَبَّابٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَبِيتُ اللَّيَالِيَ الْمُتَتَابِعَةَ طَاوِيًا وَأَهْلُهُ لاَ يَجِدُونَ عَشَاءً وَكَانَ أَكْثَرُ خُبْزِهِمْ خُبْزَ الشَّعِيرِ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
