Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that a man migrated from Yemen and came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! I have migrated. The Messenger of Allah (peace and blessings be upon him) said: You have left shirk, but you will have to strive in the way of Allah. Do you have any relatives in Yemen? He said: My parents. You asked: Did they give you permission? He said: No! You said: Go back and seek their permission; if they both give permission, then perform jihad, otherwise treat them with kindness.
