Book 2, Hadith 51
Arabic hadith text
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ حَرْمَلَةَ الأَسْلَمِيِّ، أَنَّهُ قَالَ رَأَيْتُ سَعِيدَ
Translation
Yahya related to me that Abd ar-Rahman ibn Harmala al-Aslamisaid, "I saw Said ibn al-Musayyab with his nose bleeding and bloodpoured out of it so that his fingers were all red from the bloodcoming out of his nose, and he prayed without doing wudu."
