Mohammed bin Suleiman Al-Dailami, through a reliable chain of narrators said, "I mentioned the devotion, religious acts and piety of a certain individual to Hazrat Imam Jaffer as-Sadiq A.S. The Imam asked, "What about his common sense?" I said, "I have no idea." The Imam said, "The rewards depends upon the degree of his common sense." Then the Imam A.S. exemplified this principle saying, "A descendent of Israeel used to worship Allah in an Island, verdant, full of greenery and blossoming trees and an abundant supply of pure and fresh water. One of the angels happened to pass that way and (being impressed by the sincerity of the devotion of the worshipper) prayed: "O my Lord! show me the reward destined for this servant of Thine." Allah, the Elevated One, showed him that (reward). The angel thought that the reward was less than what the worshipper deserved. Allah, the Elevated One, then inspired the angel to befriend him. The angel approached the worshipper in a human form. The worshipper asked, "Who are you?" He said, "I am also a devoted worshipper. I have been told about your worship and this place of yours in this area. Therefore I have come to you to worship Allah in your company." That day the angel remained with the worshipper. The following morning, the angel addressed the worshipper saying, "This place of yours is excellent and is most suitable for worship." The worshipper remarked, "There is, however, one drawback in this place." The angel asked, "And what is that?" He said, "Our Lord does not have any quadrupeds. If he had a donkey, I would have let him graze in this place because all this grass is just being wasted." The angel then asked him, "So your Lord does not possess a donkey?" He replied, "If he had a donkey, a verdant greenery would not have been wasted." Allah then revealed to the angel by means of inspiration, "I reward (My servants) on the basis of their common sense."
