Among what Allah, the Mighty and High, revealed to Musa was: O Musa, I have not crated a creation more beloved to Me than My believing servant. Verily, I try him with what is good for him, and cure him for what is good for him. I know what is best for My Servant in his affairs. Hence, he should be patient with My Trials. He should thank me for My Bounties. And he should be pleased with My Destiny. If he act for My Pleasure, and obeys My Command, I will count hi among the truthful ones.
