Sayyiduna Kurdam bin Sufyan says that he asked the Prophet (peace be upon him) about the ruling of a vow which he had made during the time of ignorance. The Prophet (peace be upon him) asked: Did you make that vow for any idol or stone? He replied: No, rather I made it for Allah. The Prophet (peace be upon him) said: Then fulfill the vow you made for Allah; slaughter an animal at the place called Bawna and fulfill your vow.
