وَمَآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَـٰبَ إِلَّا لِتُبَيِّنَ لَهُمُ ٱلَّذِى ٱخْتَلَفُوا۟ فِيهِ ۙ وَهُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ Qur’an An-Nahl (16:64)Wama anzalna AAalayka alkitaba illa litubayyina lahumu allathee ikhtalafoo feehi wahudan warahmatan liqawmin yuminoona
But the path of duty before Allah's Messenger is clear. He is sent with the Revelation (the Qur-an) for three express purposes; (1) that he should bring about unity among the jarring sects, for the Gospel of Unity, while preaching the One True God, leads also to the unity of mankind; (2) that the revelation should be a guide to right conduct; and (3) that it should show the path of repentance and Salvation, and thus be the highest mercy to erring sinners.
