A few other stories of pranks I found:
Once it so happened that the Prophet stayed longer than usual at the quarters of Zainab bint Jahsh, for she had received from somewhere some honey which the holy Prophet liked very much. "At this", says 'Aisha, "I felt jealous, and Hafsa, Sawda, Safiya, and I agreed among ourselves that when he visits us each of us would tell him that a peculiar odour came from his mouth as a result of what he had eaten, for we knew that he was particularly sensitive to offensive smells". So when his wives hinted at it, he vowed that he would never again use honey. Thereupon these verses were revealed reminding him that he should not declare to himself unlawful that which Allah had made lawful to him.
Once while traveling, Aisha and Safiyyah traded places to play a practical joke on Rasoolullah (SAW). Not realizing they had changed places, Rasoolullah (SAW) went to talk with who he thought was Aisha. Unfortunately for Aisha, Rasoolullah (SAW) ended up spending the night with Safiyyah, which irked Aisha.
