From now on we have a brief reference to an incident of Abraham and his nephew, Lot, and to some other great apostles, and their mutinous people:ِ

      ``And inform them of the guests of Abraham, when they came to him and saluted by saying, ``PEACE''.''

      His guests were angels in the guise of men with uncommon appearance. When they refused Abraham's hospitality, and did not even touch the food that he and his wife prepared for them, Abraham felt some sort of awe, due to suspicion and anxiety. This was because, it has always been a custom of the Eastern People that when some one eats what they call the salt and bread of some one else, he restrains himself from harming the host for owing fidelity and observance of duty. So Abraham said to his unknown guests:ِ

      ``We are afraid of you!''

      Soon the angels removed Abraham's awe, by introducing themselves and giving the prophet a very good news too!

      The birth of a son endowed with knowledge and wisdom, in the old age to a man who has had no children was indeed a wonderful glad-tiding.

      So when Abraham revived from a state of suspicions and anxiety, he asked the angels a question about their mission:ِ

      ``He said, then, what is your commission o, Messengers?''

      They informed Abraham that, they were sent to destroy the guilty people of Lot. Meanwhile they assured Abraham that they would deliver the folk of Lot, except his wife who had to perish among the guilties.
