اَلَيْسَ اللّٰهُ بِكَافٍ عَبْدَهٗۗ وَيُخَوِّفُوْنَكَ بِالَّذِيْنَ مِنْ دُوْنِهٖۗ وَمَنْ يُّضْلِلِ اللّٰهُ فَمَا لَهٗ مِنْ هَادٍۚ ( الزمر: ٣٦ )
Alaisal laahu bikaafin 'abdahoo wa yukhawwi foonaka billazeena min doonih; wa mai yudlilil laahu famaa lahoo min haad (az-Zumar 39:36)
Is not Allah sufficient for His Servant [i.e., Prophet Muhammad (^)]? And [yet], they threaten you with those [they worship] other than Him. And whoever Allah leaves astray – for him there is no guide. (Az-Zumar  : 36)

Is Allah not sufficient for (the protection of) His slave? They are frightening you of those (false gods whom they worship) other than Him. Whomsoever Allah would let go astray, for him there is no one to guide.
