"Ibn al-Qasaar and our shaykh said: the Sahaabah agreed that [the person who does homosexual acts] should be killed, but they differed as to how he should be killed. Abu Bakr al-Siddeeq said that he should be thrown down from a cliff. ‘Ali (may Allaah be pleased with him) said that a wall should be made to collapse on him. Ibn ‘Abbaas said, they should be killed by stoning. This shows that there was consensus among them that [the person who does homosexual acts] should be killed, but they differed as to how he should be executed." - Sheikh Muhammed Salih Al-Munajjid
