أَخْبَرَنَا الْحُسَيْنُ بْنُ حُرَيْثٍ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي يَزِيدَ، قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ، يَقُولُ أَنَا مِمَّنْ، قَدَّمَ النَّبِيُّ صلى الله عليه وسلم لَيْلَةَ الْمُزْدَلِفَةِ فِي ضَعَفَةِ أَهْلِهِ ‏.‏

It was narrated Abbas said

"I was one those whom the Prophet sent ahead on the night of Al-Muzdalifah among the weak ones of his family."
