UDL: The Nature of Truth and Reality

2: 255. Allah! there is no Allah but He the living the Self-subsisting Eternal. No slumber can seize him nor sleep.  His are all things in the heavens and on earth.  Who is there can intercede in His presence except as He permits?  He knows what (appears to his creatures as) before or after or behind them.  Nor shall they compass aught of his knowledge except as He wills.  His throne doth extend over the heavens and the earth and He feels no fatigue in guarding and preserving them.  For He is the Most High the Supreme (in glory). 

Narrated Abu Huraira: Prophet Muhammad ordered me to guard the Zakat revenue of Ramadan. Then somebody came to me and started stealing of the foodstuff. I caught him and said, “I will take you to Allah’s Apostle!” Then Abu Huraira described the whole narration and said: That person said (to me), “Please don’t take me to Allah’s Apostle and I will tell you a few words by which Allah will benefit you. When you go to your bed, recite Ayatul Kursi, (2.255) for then there will be a guard from Allah who will protect you all night long, and Satan will not be able to come near you till dawn.” When the Prophet heard the story he said (to me), “He (who came to you at night) told you the truth although he is a liar; (Do you know who it was?) and it was Satan.”
