Musannaf Ibn Abi Shaybah 38092 — Reports from Abu Ubaydah

Abu Ubaydah says: Allah Almighty says: What is the matter with those people who seek to gain understanding without worshipping Me? They wear sheepskins, yet their hearts are more bitter than aloes (a bitter fruit). Is it about Me that they are deceived, or is it Me that they try to deceive? I swear by Myself that I will put them to a trial in this world that will leave even the forbearing among them bewildered and at a loss.
