Belief In Divine Will & Predestination
(Qada Wa Qadr)
Influence of our actions on predestination
One of the Prophet’s companions posed a question: “O Allah's Messenger! Shall we depend upon what is written for us and give up doing (good) deeds? For whoever among us is destined to be fortunate (in the Hereafter), will join the fortunate peoples and whoever among us is destined to be miserable will do such deeds as are characteristic of the people who are destined to misery.” The Prophet ﷺ replied, “Those who are destined to be happy (in the Hereafter) will find it easy and pleasant to do the deeds characteristic of those destined to happiness, while those who are to be among the miserable (in the Hereafter), will find it easy to do the deeds characteristic of those destined to misery.” Then the Prophet ﷺ recited the following verse of the Quran to help explain better: “As for him who gives (to others), keeps his duty to Allah, and believes in the Best reward from Allah, We will make smooth for him the path of ease. But he who is a greedy miser and thinks himself self-sufficient, and gives the lie to the Best reward from Allah we will make smooth for him the path for evil.”
When Allah ﷻ says that He ‘will make smooth for him the path of ease or evil’ is because He observes everything that we say or do, in fact He is aware of each and everything our deep conscious inside of us whispers every second of our lives, “He is aware of the [most] stealthy glance, and of all that the hearts would conceal.” Therefore, there is no way to escape His knowledge of our intention and free will and depending on how we make use of them, He writes our destination, as “with Him is the Mother of the Book.”
