In this campaign the Muslims captured a large number of war prisoners. As Abu Darda saw these prisoners, Abu Darda wept bitterly. Some one asked Abu Darda as to why he was weeping when it was an occasion for the Muslims to rejoice. Abu Darda said, "I am weeping at the fate of people who disobey God. When they disobey God they come to grief like these people. I fear for the Muslims, lest by disobeying God they may also invite such a grim fate for themselves. "
