Utbah bin Ammar reports, through Ibn Ayyash, this statement of his father: I came to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) and said: "Some people of the tribe and some of our neighbours are fasting today." Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) asked: "Upon sighting the new crescent?" I replied: "No." He said: "That I leave a day of Ramadan unfasted and then make it up is dearer to me than that I fast a day of Sha'ban."
Al-Tabarani recorded it in al-Mu'jam al-Kabir. I have not found anyone who mentioned Utbah or his father.
