Lady Umm Hani (may Allah be pleased with her) narrates: A drink was brought before the Prophet (peace and blessings of Allah be upon him), he drank from it and gave it to me to drink, so I also drank from it. I said: O Messenger of Allah! I was fasting. The Prophet (peace and blessings of Allah be upon him) said: "A person who is observing a voluntary fast is the trustee of his own affair (the narrator is in doubt, perhaps he said: he is the master of his own affair, meaning he is the owner of his own decision), that is, if he wishes, he may continue the fast, and if he wishes, he may break it." Shu’bah narrates: I asked: Did you hear this narration from Lady Umm Hani? He said: No! This narration has been reported by our family members and Abu Salih. The narrator named Shu’bah says: I heard from Simak, he says: I met the most virtuous among the sons of Ja’dah, and he narrated this hadith to me.
