Two friends Ismail and Ibrahim were walking through the desert, as the sun was beating down on their heads, and they were thirsty for water they began to argue. The argument got more and more heated and eventually Ismail struck Ibrahim across the face. Ibrahim felt hurt inside, but without anything to say, he wrote in the sand: "Today, my best friend slapped me in the face."
They kept on walking, until eventually they came across an oasis, where they decided to stop and bathe. Ibrahim jumped in and began to wash, while Ismail sat back and relaxed. Suddenly Ibrahim began to scream and shout, he had developed a cramp and was having difficulty keeping his head above water, he was drowning.
Ismail dived in after him, and brought him gently to shore. When Ibrahim recovered from the shock, he scratched a message on a nearby stone:
"Today, my best friend saved my life"
Ismail who had saved and slapped his best friend Ibrahim, asked him, "Why, after I hurt you, you wrote in the sand, and now you write on a stone?"
Ibrahim, smiled and replied:
"When a friend hurts us, we should write his deeds in the sand, where the winds of forgiveness can blow it away, and when a friend does something good, we should engrave it in stone, where it shall remain for eternity."
