Remember Allah

"O ye who believe! Remember Allah with much remembrance; and glorify Him morning and evening."
(Al Quran 41-42)

O ye who believe! Let not your wealth nor your children distract you from remembrance of Allah. Those who do so, they are the losers.
(Al Quran 63:9)

Shaytaan (Satan) has overpowered them. So he has made them forget the remembrance of Allah. They are the party of Shaytaan (Satan). Verily, it is the party of Shaytaan (Satan) that will be the losers!
(Al Quran 58:19)
