They came and said: "You let them go without any pressure (to make them admit to their crime) or beating?" An-Nu'man said: "What do you want? If you wish, I will beat them, and if Allah brings back your goods thereby, all well and good. Otherwise I will take retaliation from your backs (by beating you) likewise." They said: "is this your ruling?" He said: "This is the ruling of Allah and His Messenger "(Daif)
