What did Hudhaifa say to the person who did not perform his bowing and prostrations perfectly according to the tradition of the Prophet Muhammad (saw)?
 Narrated Abu Wail:                     Hudhaifa said, "I saw a person not performing his bowing and prostrations perfectly. When he completed the prayer, I told him that he had not prayed." I think that Hudhaifa added (i.e. said to the man), "Had you died, you would have died on a tradition other than that of the Prophet Muhammad."
