Is it a condition for a non-Muslim man to have been Muslim for six months before marrying a Muslim woman?

Islam abrogates what came before it. So, whoever embraces Islam with a true conversion is forgiven for what occurred before his Islam. He is permitted to marry a Muslim woman, whether he is a recent convert or has been Muslim for a long time, and whether he previously adhered to another religion or not. He is not compelled to delay marriage to a Muslim woman unless his conversion is a trick to get married. If he converts and his character improves, his marriage should not be delayed; for the Messenger of Allah, peace and blessings be upon him, said: "If someone whose religion and character you approve comes to you seeking marriage, then marry him. If you do not do so, there will be tribulation on earth and widespread corruption."
