His wife, Khadija, and his uncle Abu Talib - the biggest supporter and backer of Muhammad - died in 619 CE, and he was called the year of grief. So Abu Lahab took over the leadership of Bani Hashem after Abu Talib, and after that the protection of Bani Hashem for Muhammad diminished, and the Quraish’s harm increased to him. This prompted him to go out to Al-Taif to invite them, hoping to shelter him and support him over his people, but they hurt him and threw stones at him and refused his invitation, and only Tafil bin Amr Al-Dossi was recognized (who called his people and converted some of them and resided in his country until Khaybar conquered and then brought them in about eighty homes).
