Hazrat Muhammad bin Abi Al-Mujahid says that there was a disagreement between Hazrat Abu Burdah and Hazrat Abdullah bin Shaddad regarding Bai' Salam. He sent me to Ibn Abi Awfa, so I asked him, and he said: During the time of Hazrat Muhammad صلی اللہ علیہ وسلم and the caliphate of Hazrat Abu Bakr (may Allah be pleased with him), we used to conduct Bai' Salam in wheat, barley, and raisins, and we do not know of any companion who said yes or no about it.
