And when Our clear signs are recited unto them, then those who hope not to meet Us begin to say, 'bring a Quran other than this, or alter it. Say you, 'it is not for me to change it on my own accord. I only follow, what is revealed to me if I disobey my Lord, then I fear the torment of the great Day.[10:15]
It is narrated on the authority of Jabir that Nu'man b. Qaufal came to the Holy Prophet (may peace be upon him) and said: Would I enter Paradise if I say the obligatory prayers and deny myself that which is forbidden and treat that as lawful what has been made permissible (by the Shari'ah)? The Holy Prophet (may peace be upon him) replied in the affirmative.
