Musannaf Ibn Abi Shayba 23:110

Waki' narrated to us, he said: Al-A'mash narrated to us, from Salamah ibn Kuhayl, from Habbah ibn Juwayn al-'Arani, he said: We were with Salman, and the enemy had drawn up in ranks against us. He said: "These are the believers, and these are the hypocrites, and these are the polytheists. Allah grants victory to the hypocrites through the supplication of the believers, and Allah supports the believers through the supplication of the hypocrites."
