When the Prophet, peace and blessings be upon him, had entered it, he later informed that he wished he had not entered it, out of fear of burdening his ummah after him. And this is like his, peace and blessings be upon him, leaving off some voluntary acts, which he used to love to do, intending to make things easier for his ummah, peace and blessings be upon him.

Lady Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) left from me in a very happy and cheerful state. Then he returned to me and he was very sad. I said, "O Messenger of Allah (peace and blessings be upon him), you left me very happy and delighted, and now you appear sorrowful." He (peace and blessings be upon him) said: "I entered the Sacred Ka'bah, and I wish that I had not entered it. I fear that I have put my Ummah into difficulty and hardship after me."
