«من الغيرة ما يحب الله ومنها ما يكره الله فأما ما يحب فالغيرة في الريبة وأما ما يكره فالغيرة في غير ريبة»
The Prophet (peace and blessings be upon him) said:
"Among jealousy there is some that Allah loves and some that Allah dislikes. The jealousy that Allah loves is jealousy where there is suspicion, and the jealousy that Allah dislikes is jealousy without any suspicion."
