Chapter 2: Purity - كتاب الطهارة
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْمُجَبَّرِ، أَنَّهُ رَأَى سَالِمَ بْنَ عَبْدِ اللَّهِ يَخْرُجُ مِنْ أَنْفِهِ الدَّمُ حَتَّى تَخْتَضِبَ أَصَابِعُهُ ثُمَّ يَفْتِلُهُ ثُمَّ يُصَلِّي وَلاَ يَتَوَضَّأُ .
Yahya related to me from Malik from Abd ar Rahman ibn al-Mujabbar that he saw Salim ibn Abdullah with blood running from his nose so that his fingers were all coloured red. Then he rubbed it and prayed without doing wudu.
