64 Preface وَما أَنزَلنا عَلَيكَ الكِتابَ إِلّا لِتُبَيِّنَ لَهُمُ الَّذِي اختَلَفوا فيهِ ۙ وَهُدًى وَرَحمَةً لِقَومٍ يُؤمِنونَYusuf AliAnd We sent down the Book to thee for the express purpose, that thou shouldst make clear to them those things in which1 they differ, and that it should be a guide and a mercy to those who believe.But the path of duty before God’s Messenger is clear. He is sent with the Revelation (the Qur-ān) for three express purposes: (1) that he should bring about unity among the jarring sects, for the Gospel of Unit)', 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.
