Narrated Aisha, Ummul Mu'minin: I said to the Prophet (ﷺ): It is enough for you in Safiyyah that she is such and such (the other version than Musaddad's has:) meaning that she was short-statured. He replied; You have said a word which would change the sea if it were mixed in it. She said: I imitated a man before him (out of disgrace). He said: I do not like that I imitate anyone even if I should get such and such.
