أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ ثَوْرٍ، عَنْ خَالِدِ بْنِ مَعْدَانَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِرَجُلٍ " هَلُمَّ إِلَى الْغَدَاءِ الْمُبَارَكِ " . يَعْنِي السَّحُورَ .
It was narrated that Khalid bin Ma'dan said: "The Messenger of Allah said to a man: 'Come to the blessed breakfast, - meaning Sahur." '
