Musannaf Ibn Abi Shaybah 32438 — Book of Faith

Hubbah bin Juwayn al-Urani (may Allah have mercy on him) said: We were with Sayyiduna Salman al-Farisi (may Allah be pleased with him), standing in ranks facing the enemy, when he (may Allah be pleased with him) said: These people are the believers, these are the hypocrites and these are the polytheists. Allah will help the hypocrites by the supplications of the believers, and Allah will support the believers by the strength of the hypocrites.
