Ismail bin Abi Khalid said: I heard Amir (al-Sha'bi) saying that a man asked Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) for a fatwa, saying: O Abu al-Mundhir! What do you say about this matter? He replied: Son! The matter about which you are asking for a fatwa, has it actually occurred? He said: No. He replied: Then give me respite until it happens, then we will consider it and give you a fatwa.
