Bear then patiently what they say, and glorify your Lord by the praising of Him before the rising of the sun and before its setting And during hours of the night do also glorify (Him) and during parts of the day, that you may be well pleased.
Five time a day, we should glorify our Lord, before sunrise and before sunset, during night and othe parts of day. And that will help us to be happy and pleased. Also if we avoid to remember God we will have problem in this world as well as the other world:
And whoever turns away from My Reminder, his shall surely be a straitened life, and We will raise him on the Day of Resurrection, blind.
So If one want to be happy and his life not to be straitened, then should remember God at least five time a day!
