أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنِ ابْنِ عَجْلاَنَ، قَالَ حَدَّثَنِي عَاصِمُ بْنُ عُمَرَ بْنِ قَتَادَةَ، عَنْ مَحْمُودِ بْنِ لَبِيدٍ، عَنْ رَافِعِ بْنِ خَدِيجٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ أَسْفِرُوا بِالْفَجْرِ ‏"‏ ‏.‏
Translation
It was narrated from Mahmud bin Labid, from some men among his people who were of the Ansar, that the Messenger of Allah (ﷺ) said

"The more you delay Fajr, the greater the reward."
