The Prophet (peace be upon him) disapproved of two persons competing with one another to secure marriage with the same girl. This is because such a situation is likely to develop bitter enmity between two Muslim brothers.

"A believer is a brother of a believer. Hence it is not lawful for him to bargain upon the bargain of a brother, nor propose for (the hand of a girl) after the marriage proposal of his brother, until the latter (voluntarily) withdraws the proposal."

Imam Abu Hanifa, Imam Shafi'i, and Imam Malik, all hold the view that it is a sin to put a proposal of marriage against the proposal of another Muslim brother. However, if a marriage is contracted in this wrongful way it will be sufficient if the second suitor who was successful seeks the forgiveness of the first suitor and of Allah. But Imam Dhahiri considers such a marriage void. It is respectfully submitted that the former view is more rational and sound.
