It was narrated from Abu Hurairah:
that the Messenger of Allah said: "If there comes to you one with whose character and religious commitment you are pleased, then marry (your daughter or female relative under your care) to him, for if you do not do that there will be Fitnah in the land and widespread corruption.'"
