Narrated Ibn `Abbas: Regarding the Verse: And among men is he who worships Allah's as it were on the very edge. (22.11). A man used to come to Medina as if his wife brought a son and his mares produces offspring. He would say, This religion (Islam) is good, but if his wife did not give birth to a child and his mares produced no offspring, he would say, This religion is bad.
