أَلَيْسَ اللَّهُ بِكَافٍ عَبْدَهُ ۖ وَيُخَوِّفُونَكَ بِالَّذِينَ مِن دُونِهِ ۚ وَمَن يُضْلِلِ اللَّهُ فَمَا لَهُ مِنْ هَادٍ (36)
(39:36) (O Prophet), does Allah not suffice for His servant? They frighten you with others apart from Him, *55 although he whom Allah lets go astray, none can guide him to the Right Way.
*55) The disbelievers of Makkah used to say to the Holy Prophet, "You behave insolently in respect of our deities and utter rude words against them : you do not know how powerful they are and what miraculous powers they possess. Anybody who dishonoured them was ruined. If you also do not desist from what you say against them, you too will be annihilated. "
