Pick a day when you’ll try to be grateful to Allah.
Allah deserves our thanks all the time, and we shouldn’t limit our thanks in any way… but set aside one day when you’re more grateful than normal. A day when you wake up and go to sleep, and your whole goal is to be grateful to Allah, to thank Him, subhanahu wa ta’ala, as much as you possibly can.
When you rise from sleep, thank Allah with all your heart for the new day, the chance to start over. The chance to grow and get closer to Him. Thank Him for the air you’re taking in with your lungs, and for each breath He’s given you – without having to do anything on your part – since the day you were born.
