وَحَدَّثَنِي ، عَنْ مَالِك ، أَنَّهُ بَلَغَهُ ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ ، " كَانَ يَرْعُفُ فَيَخْرُجُ فَيَغْسِلُ الدَّمَ عَنْهُ ، ثُمَّ يَرْجِعُ فَيَبْنِي عَلَى مَا قَدْ صَلَّى "
Imam Malik (may Allah have mercy on him) received the information that when Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) would have a nosebleed, he would go outside, then (only) clean the blood, then return (without performing ablution), and would continue from where he had left off in the prayer (and would complete the remaining prayer).
