16-Surah An-Nahl ( The Bees ) 64
And We have not revealed to you the Book, [O Muhammad], except for you to make clear to them that wherein they have differed and as guidance and mercy for a people who believe.
وَمَا أَنزَلْنَا عَلَيْكَ الْكِتَابَ إِلَّا لِتُبَيِّنَ لَهُمُ الَّذِي اخْتَلَفُوا فِيهِ ۙ وَهُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ
Quran's Tafhim ( explanation)
*53) That is, "This Book has afforded them an excellent opportunity to resolve their differences which have been caused by the superstitious creeds of their forefathers, and which have divided, them into warring factions. They can then unite on the permanent basis of the Truth presented by the Qur'an, but those foolish people preferring their former condition even after the coming of this blessing, shall meet with disgrace and torment. On the other hand, only those, who believe in this Book, will find the Right Way and blessed with mercy and favours from AIlah" .
