13. Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid said: Muhammad ibn al-Hasan alSaffar said, on the authority of Ibrahim ibn Hashim, on the authority of al-Hasan ibn Mahbub, on the authority of Malik ibn `Atiyyah, on the authority of Dawud ibn Farqad that Abu `Abd Allah al-Sadiq said: 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.
