A letter to Amr bin Aas.
Undoubtedly you have subordinated your religion to the worldly power, pomp and wealth provided to you by a person whose apostation and scepticism are not hidden from anybody. He and his ways are known to everybody. He sullies the reputation as well as the character of those who keep company with him. He tries to deceive sober and sedate people. For the sake of remnants and crumbs of bread left over at his table, you have attached yourself to him. You are following him like a dog which follows a tiger, frightfully looks at its paws and waits to live upon the refuse which it leaves of its kill.
In this way you have lost your self-respect and honour in this world and your salvation in the next. You have ruined your present and future. Had you followed the true path, you would have secured success in this world as well as in the Hereafter.
