It was
narrated that ‘Aishah said:
“The Messenger of Allah (ﷺ) went
out delighted, then he came back to me sad. I said: ‘O Messenger of
Allah, (why did) you go out happy and come back sad?’ He said: ‘I
entered the Ka’bah, and I wish that I had not done that, because I
am
afraid that I may have caused difficulty for my nation after I am
gone.’”
