The Spoils of War - 8:39
Fight them until they abolish oppression and oppression and make the religion the religion of Allah alone. If they cease hostility, surely Allah is All-Seeing of what you do.
There is no compulsion in religion:
The Cow/2:256
There is no compulsion in religion. So the truth is separated from error. Whoever disbelieves in Taghut (despots and evil doctrines) and believes in Allah, he has clung to an unbreakable and firm bond. Allah Hears, Knows.
The Women/4:80
He who follows the messenger follows Allah. Whoever turns away, let him turn away; We have not sent you as a watchman over them.
The Cattle/6:104
There has come to you enlightening knowledge from your Lord. Whoever sees is for his own benefit and whoever is blind is for his own loss. I am not a watchman over you.
The Cattle/6:107
If Allah had willed, they could not associate partners. We have not made you a guardian over them, nor are you their advocate.
Prophet Jonah/10:99
Had your Lord willed, all those on the earth would have believed. Then will you force the people to believe?
Prophet Hud/11:27
"The leaders of his people who disbelieved said, "We see that you are only a man like us, and we see that no one follows you except the shallow-minded rabble among us. Nor do we see any superiority in you over us. On the contrary, we think that you are liars."
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 Cave/18:29
"Say, "This truth is from your Lord."Let whoever wishes believe and whoever wishes disbelieve. We have prepared for the wrongdoers a Fire that will surround them, and whenever they cry out for help, they will be offered water that scalds their faces like concentrated acid. What an evil drink, what an evil end!"
The Companies/39:15
"Say, "You serve whomsoever you wish besides Him."Say, "The real losers are those who make themselves and their families lose on the Day of the Hereafter."This is the obvious loss"
Council/42:48
If they turn away, We have not sent you to them as a guardian; your duty is only to inform. When We give man a taste of mercy from Us, he rejoices in it; but when evil befalls them as a result of what they themselves have done, then man becomes ungrateful.
The Letter Qaf/50:45
We know well what they talk about. You are not a tyrant over them. Admonish those who fear My warnings with this Qur´an.
The Overwhelming/88:21
Remind them, for you are a reminder.
The Overwhelming/88:22
You will not force them.
