The greatest reward: Allah's eternal satisfaction with them

Allah has promised the men and women of the believers Gardens with rivers flowing under them, remaining in them timelessly, for ever, and fine dwellings in the Gardens of Eden. And Allah's good pleasure is even greater. That is the great victory. (Surat at-Tawba: 72)

The greatest spiritual pleasure experienced by believers when they enter the Garden is the reality that from that moment on Allah is pleased with them, that He loves them, that He will never punish them, and that they will be His friends for eternity. To have gained Allah's approval will be the source of a joy and happiness infinitely superior to any earthly comparison. Allah's pleasure is what brings the ultimate sweetness to the blessings of the Garden. Although the rewards of the Garden are wonderful in themselves, what is more delightful still is the joy of being affirmed by The Lord of all the Worlds as being worthy of receiving His kindness. The Qur'an states:

O self at rest and at peace, return to your Lord, well-pleasing and well-pleased! Enter among My servants! Enter My Garden. (Surat al-Fajr: 27-30)
