Al-Sha'bi (may Allah have mercy on him) narrates from Sayyiduna Ali (may Allah be pleased with him) that there is no dowry less than ten dirhams. Sufyan (may Allah have mercy on him) said: Dawud, Dawud? And he kept rejecting it. I said: Shu'bah (may Allah have mercy on him) narrates from him. So he struck his forehead and said: Dawud, Dawud?
