Masruq narrates that Sayyidah Aishah (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) did something and allowed a concession in it. Then he (peace and blessings be upon him) came to know that some people disliked it and kept away from it. He (peace and blessings be upon him) said: "What is the matter with people that a matter in which I have allowed a concession reaches them from me, and they dislike it and keep away from it? By Allah, I know Allah better than they do, and I fear Allah more than they do."
