In this video we are encouraged to be grateful both in times of abundance and during struggles and deprivation.
When we face hardships, we should remain steadfast to be able to get the great rewards of forbearance.
On the other hand, being grateful in times of prosperity and blessings is an affirmation of our faith.
We should praise Allah even if the physical blessing is missing. After all, Praise in itself is a blessing.
