On the occasion when Nabi Musaa (alayhis salaam) was on his way to Mount Tur to observe I’tikaaf of 40 days, to commune with Allah Ta’ala, and to receive the revelation of the Tauraah, he met an old man sitting on a rock crying profusely. Pitying the old man, Nabi Musaa (alayhis salaam) enquired of the reason for his grief.
The old man replied that he was Shaitaan and he was crying because Allah’s mercy extended on all beings except him. Although he too was Allah’s creature, he is being excluded from Allah’s mercy, hence he was shedding so many tears. Nabi Musaa (alayhis salaam) promised to raise the matter with Allah Ta’ala on Mount Tur.
