  Translation

135. And they say, "Be Jews or Christians, then you will be guided." Say (to them, O Muhammad Peace be upon him ), "Nay, (We follow) only the religion of Ibrâhim (Abraham), Hanifa [Islâmic Monotheism, i.e. to worship none but Allâh (Alone)], and he was not of Al-Mushrikûn (those who worshipped others along with Allâh - see V.2:105)."
