Do you await a day in which it would be no longer difficult to go against one's desires?

“Do you await a day in which it would be no longer difficult to go against one's desires? This is a day that Allah has never created, and nor will He ever create it! For the Paradise will always be covered with difficulties, and difficulties will never be easy upon the soul to bear. The existence of such is impossible!

How have you received this tomorrow of yours? Did you not know that “tomorrow” which is now today is really yesterday? Verily that which you're incapable of achieving today, tomorrow you will be even further incapable of achieving!

This is because desires are like a firm tree which we have been enslaved to uproot. If one is incapable of fighting his desires and he delays this battle, it is like a person who delays uprooting a tree while he is young and strong; knowing the fact that this procrastination is only giving way for the tree to grow stronger and firmer, while he himself is growing weaker and weaker.”

This ayat was revealed in Makkah, when the da'wah first went public and the challenge to the Muslims was at its worst. [1]  The passage follows a description of the prophets of Allah and their offspring whom Allah had guided as, Allah says,
