The eminent Muslim scholar and renowned Da`iyah, Sheikh `Abdel Khaliq Hasan Ash-Shareef, states:
“Almighty Allah says, ‘And they who believe and whose seed follow them in faith, We cause their seed to join them (there), and We deprive them of naught of their (life’s) work. Every man is a pledge for that which he hath earned.‘ (At-Tur: 21) So, Allah’s mercy is limitless and based on this verse if it happens that one of the spouses was in a lower rank in Paradise, he or she will be elevated to a higher level wherein the other spouse resides out of Allah’s mercy.
