Muwatta Imam Malik Book of Fasting, Hadith 31

Yahya related to me from Malik from Ibn Shihab that Sad ibn Abi Waqqas and Abdullah ibn Umar used to be cupped while they were fasting.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ سَعْدَ بْنَ أَبِي وَقَّاصٍ، وَعَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَا يَحْتَجِمَانِ وَهُمَا صَائِمَانِ .
