Musannaf Ibn Abi Shayba 3:5630

Abu Usama narrated to us, he said: Al-A’mash narrated to us, he said: Al-Minhal ibn ‘Amr narrated to us, from Sa’id ibn Jubayr, from Ibn ‘Abbas, who said: "Indeed, the Shaytan circles the servant to interrupt his prayer. When he tires him out, he blows into his posterior, so he should not depart until he hears a sound or finds a scent. And he comes to him and squeezes his penis, making him think that something has come out of him, so he should not depart until he is certain."
