"I don’t know how many people will understand if I said, in Islam, Deen is Dunya.
Deen is all things that generally pass for “Religion.”
Deen also refers to the world after death, otherwise known as Aakhirah.
Dunya is this world – all the chores, worries and responsibilities that people deal with during their tenure on earth, while they live in this world.
And in Islam, there is no daylight, as they say these days, no separation or dichotomy, between the two: the Deen and the Dunya.
It is one continuum, two closely and inseparably intertwined dimensions, of the same basic reality of a life of total submission to God Almighty.
So, you take care of one, the other will automatically take care of itself.
You take care of the Dunya, Allah will take care of the Deen and Aakhirah.
To get a fuller perspective on this equation, read the declaration by Ibrahim, Alaihis Salam, in the Qur’an:
Inna Swalaatee Wa Nusukee Wa Mahyaaya Wa Mamaatee Lillahi Rabbil 'Aalameen.
And reflect on the Hadith Sharif:
Addunya Mazra’atul Aakhirah!" (Dr. Pasha)
