The Firmest Handhold

فَمَن يَكْفُرْ بِٱلطَّـٰغُوتِ وَيُؤْمِنۢ بِٱللَّهِ فَقَدِ ٱسْتَمْسَكَ بِٱلْعُرْوَةِ ٱلْوُثْقَىٰ لَا ٱنفِصَامَ لَهَا ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ٢٥٦

So whoever renounces false gods and believes in Allah has certainly grasped the firmest, unfailing hand-hold. And Allah is All-Hearing, All-Knowing.

(Quran 2:256)
