13:28
ٱلَّذِينَ ءَامَنُوا۟ وَتَطْمَئِنُّ قُلُوبُهُم بِذِكْرِ ٱللَّهِ ۗ أَلَا بِذِكْرِ ٱللَّهِ تَطْمَئِنُّ ٱلْقُلُوبُ
alladhīna āmanū wataṭma-innu qulūbuhum bidhik'ri l-lahi alā bidhik'ri l-lahi taṭma-innu l-qulūbu
those who have faith and whose hearts find peace in the remembrance of God- truly it is in the remembrance of God that hearts find peace-
Those who believed (in the Oneness of Allâh - Islâmic Monotheism), and whose hearts find rest in the remembrance of Allâh: verily, in the remembrance of Allâh do hearts find rest.
