Hazrat Hibban bin Zaid narrates... He was a close friend of Hazrat Nu'man and Hazrat Nu'man (may Allah be pleased with him) had appointed him as the governor at the place of Nabk... He says that he heard Hazrat Nu'man saying: Beware! The deeds of Allah's agents are guaranteed by Allah. Beware! The deeds of the children of Adam are not owners of their own guarantee. The narrator says that when Hazrat Nu'man descended from his pulpit, he (Hibban) came to him and wanted to resign. Hazrat Nu'man asked: What has happened to you? He replied: I heard you saying such and such.
