Abu Razin reported: Abu Hurairah (RA) came to us and he struck his forehead with his hand and said: Behold I you talk amongst yourself that I attribute wrongly to Allah's Messenger (ﷺ) (certain things) in order to guide you to the right path.

I bear testimony to the fact that I heard Allah's Messenger (ﷺ) saying: When the thong of any one of you is broken, he should not walk in the second one until he has got it repaired.
