Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: "By the One besides whom there is no other god! When a servant holds a good opinion of Allah Almighty, Allah Almighty grants him according to his opinion. The reason for this is that all good is in His hand of power."
Imam al-Tabarani recorded this narration as a mawquf narration (stopping at the Companion), and its narrators are the narrators of the Sahih, except that the narrator named al-A'mash did not live in the time of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him).
