Importance of remembrance of Allah (dhikr)

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تُلْهِكُمْ أَمْوَٰلُكُمْ وَلَآ أَوْلَـٰدُكُمْ عَن ذِكْرِ ٱللَّهِ ۚ وَمَن يَفْعَلْ ذَٰلِكَ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْخَـٰسِرُونَ

O you who have believed, let not your wealth and your children divert you from the remembrance of Allāh. And whoever does that - then those are the losers.
