(Al-Hijr) 15 : 77
إِنَّ فِي ذَٰلِكَ لَآيَةً لِلْمُؤْمِنِينَ

Indeed, that is a sign for the believers.

The believers are the vicegerents of the Three-Time-Knower Lord. He is having the confirmed belief that the Lord has already decided whatever happens in the universe and is recorded in his Book Adhikr. He keeps the remembrance of Lord every time for not affecting calamities, disasters, and diseases in this world; and he always praises the Lord with the soul as: “All praise is to Lord except in the state of Fire” as explained in verse 1: 1. See explanation 3: 190-191; 9: 71-72 and 11: 120.
