Sayyiduna Abu Hurairah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "When a fasting person vomits unintentionally, there is no making up (qada) upon him, but if he vomits deliberately, then he must make up (the fast)." Isa bin Yunus said: The people of Basra believe that Hisham bin Hassan made a mistake in this hadith, which is the cause of the disagreement.
