Al-An'am 6:117

Inna rabbaka huwa aAAlamu man yadilluAAan sabeelihi wahuwa aAAlamu bilmuhtadeen

Indeed, your Lord is most knowing of who strays from His way, and He is most knowing of the [rightly] guided.

Surely, your Lord is best aware of those who go astray from His way, and He is best aware of those who are on the right path.
