It is narrated from Hammam, he says that Imam Qatadah was asked about the person who has intercourse with his wife from behind. He said: Amr bin Shu'aib narrated to us from his father, and he from his grandfather, Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them), that the Messenger of Allah (peace and blessings be upon him) said: This is a lesser degree of sodomy. Sayyiduna Abu Darda (may Allah be pleased with him) said: Only a disbeliever can do this act.
