Appears 4 times in the Quran.
11:56 إِنِّى تَوَكَّلْتُ عَلَى ٱللَّهِ رَبِّى وَرَبِّكُم مَّا مِن دَآبَّةٍ إِلَّا هُوَ ءَاخِذٌۢ بِنَاصِيَتِهَآ إِنَّ رَبِّى عَلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ
Surely I rely on Allah, my Lord and your Lord; there is no living creature but He holds it by its forelock; surely my Lord is on the right path.
The guilty shall be recognized by their marks, so they shall be seized by the forelocks and the feet.
Nay! if he desist not, We would certainly smite his forehead,
A lying, sinful forehead.
