The Forgiver - 40:15
The Raiser of the Degrees, the Owner of Governance. He sends down His revelation of His commands to whom He wills among His servants to warn them of the Day of Meeting.
Prophets, each endowed with different abilities:
The Cow/2:253
And We favored some of those messengers more than others, for example, with some Allah spoke, and with some He raised them in degrees. We gave clear proofs to Jesus son of Mary and supported him with the Holy Spirit. Had Allah willed, those who came after them would not have quarrelled with one another after clear proofs had come to them. But they differed. Some believed and some disbelieved. Had Allah willed, they would not have fought one another. But Allah does what He wills.
The Cattle/6:83
This is the method of argument We gave to Abraham to use against his people. We raise whom We will in degrees. Your Lord is Wise, Knowing.
Prophet Joseph/12:76
(Joseph) started from their burdens before his brother´s burden, and then he took the water-pot out of his brother´s burden. We had taught Joseph such a plan. Had he followed the king´s law, he could not have detained his brother, except if Allah willed. We raise whom We will in degrees. Above every knower is a better knower.
