And His Almighty's saying: {Then do they await except the way of the former peoples? But you will never find in the way of God any change, and you will never find in the way of God any alteration.} (Fatir: 43).

And His Almighty's saying in Surat Al-An'am: {And the word of your Lord has been fulfilled in truth and in justice. None can alter His words, and He is the Hearing, the Knowing.} (Al-An'am: 115).

And His Almighty's saying: {And they were not commanded except to worship God, [being] sincere to Him in religion.} (Al-Bayyinah: 5).

And He Almighty said in Surat Ar-Rum: {But those who wrong follow their [own] desires without knowledge. Then who can guide one whom God has sent astray? And for them there are no helpers. So direct your face toward the religion, inclining to truth (Hanifan). [Adhere to] the primordial nature (Fitrah) of God upon which He has created [all] people. No change should there be in the creation of God. That is the correct religion, but most of the people do not know. [Adhere to it], turning in repentance to Him, and fear Him and establish prayer and do not be of those who associate others with God (al-Mushrikin), [Or] of those who have divided their religion and become sects (Shi'an), every faction rejoicing in what it has.} (Ar-Rum: 29-32).
