In The Name of Allah, The Compassionate, The Merciful
Narrated byAbuHurayrah
The Messenger of Allah (peace be upon him) happened to pass by a heap of eatables (corn). He thrust his hand in that (heap) and his fingers were moistened. He said to the owner of the heap of eatables (corn): What is this? Messenger of Allah, these have been drenched by rainfall. He (the Prophet) remarked: Why did you not place this (the drenched part of the heap) over other eatables so that the people could see it? He who deceives is not of me (is not my follower).
