It is narrated from Abu Ubaidah (may Allah have mercy on him) that Allah, the Exalted, says: "What is the matter with some people that they acquire knowledge of the religion, but not for My worship? They wear the skins of sheep, yet their hearts are harder than patience itself! Are they deceiving Me? Or do they wish to beguile Me? By My oath! I will inflict upon them a trial that will astonish and confound even the wise."
