Prophet Hud - 11:28
"He said: "O my people, what if I have a clear proof from my Lord and He has given me Mercy and it is not visible to your eyes? Shall we force you to it while you do not want it?"
The Prophethood and the Book are mercy from our Lord to whom He wills:
The Stories/28:86
You did not expect that you would be given this Book, but this is a mercy from your Lord. Do not back the disbelievers.
The Women/4:54
Or do they resent what Allah has given to mankind from His bounty? But We gave to the family of Abraham the Book and wisdom, and We gave them great authority.
The Cow/2:90
Woe to those who sell their personalities to disbelieve in what Allah has sent down, not despising that Allah sends down His bounty to whom He wills of His servants! So they incurred wrath upon wrath. For the disbelievers is a humiliating torment.
Prophet Abraham/14:10
"Their messengers said: "Do you doubt Allah, Who created the heavens and the earth, and He calls you to forgive you your sins and gives you a certain period of time?"They said: "You are but men like us, and you want to turn us away from that which our forefathers used to serve. Bring us a clear authorization"."
Prophet Abraham/14:11
"And their messengers said to them: "Surely we are human beings like you. But Allah chooses whom He wills from among His servants and bestows favor upon him. It is impossible for us to bring you a certificate of authority without Allah´s permission. Believers should trust in Allah."
The Bee/16:2

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.
The Ornaments of Gold/43:30
"When the truth came to them, they said, "This is magic and we disbelieve in it."
The Ornaments of Gold/43:31
"They said: "Should not this Qur´an have been sent down to a famous and great man from those two cities?"
The Ornaments of Gold/43:32
Do they divide the mercy of your Lord? We divided between them their livelihood in the life of this world, and We made them superior to one another in rank, so that they might cause one another to work. And the mercy of your Lord is better than what they have accumulated.
