Sha'bi narrates: A married adulterer was brought before Sayyiduna Ali (may Allah be pleased with him), so Sayyiduna Ali (may Allah be pleased with him) had him flogged on Thursday, and on Friday he had him stoned. So it was said to him: "Why did you combine two punishments?" He replied: "I flogged him according to the command of Allah's Book, and I stoned him according to the Sunnah of Allah's Messenger."
