Shurayh bin Ubayd states: The people of Sham were mentioned in the presence of Sayyiduna Ali (may Allah be pleased with him), who was in Iraq at that time. The people said: "O Commander of the Believers! Curse them." Sayyiduna Ali (may Allah be pleased with him) said: "No! I heard the Prophet (peace and blessings be upon him) say: 'The Abdal (substitutes) will be in Sham; they will be forty men. Whenever one of them dies, Allah Almighty will bring another man in his place. Because of them rain will be sent down, through them help will be sought against the enemy, and because of them punishment will be turned away from the people of Sham.'"
Ahmad recorded it, and its narrators are the narrators of the Sahih, except Shurayh bin Ubayd, and he is thiqah (trustworthy); he heard from Sayyiduna al-Miqdad (may Allah be pleased with him), and Sayyiduna al-Miqdad (may Allah be pleased with him) passed away before Sayyiduna Ali (may Allah be pleased with him).
