Hadith 26
Ibrahim bin Sa’d narrates from his father: A man, while making a will, showed preferential treatment regarding his wealth to someone. So I went to Qasim bin Muhammad to consult him about this matter. Qasim informed me: I heard Lady Aisha (may Allah be pleased with her) narrate that the Prophet Muhammad (peace and blessings be upon him) also said: "Whoever introduces into this matter of ours (i.e., the religion) something which does not belong to it, it will be rejected."
