Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) passed by a heap of grain. He inserted his fingers into it and felt dampness. The Prophet (peace be upon him) said: O owner of this grain, what is this? He replied: O Messenger of Allah (peace be upon him)! Rain had fallen on it. The Prophet (peace be upon him) said: Why did you not put this (damp part) on top so that people could see it? Whoever deceives us is not from us.
