Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned the following:
It is the system of Allah Ta‘ala that if we rely on Him and seek His divine assistance in all our endeavours, then He will bless us with His divine support due to which our works will continue to prosper. Allah Ta‘ala indicates towards this in the following verse of the Quraan Majeed:
وَّ یَزِدۡکُمۡ قُوَّۃً اِلٰی قُوَّتِکُمۡ
He (Allah Ta‘ala) will increase you in strength, added to your strength. (Surah Hood v52)
For one not to make any effort and expect everything to happen is “jabriyyat” (i.e. resembling the deviated sect who felt that man does not have the ability to do anything), and to regard oneself as being in full control and rely on one’s efforts entirely is “qadriyyat” (i.e. resembling the deviated sect who felt that Allah Ta‘ala does not have any control over our actions, and we are in full control of our lives and actions).
The correct Islamic approach is in between these two wrong beliefs. In other words, the little capability and strength that Allah Ta‘ala has blessed us with, we are required to utilize it in striving to the best of our ability to fulfil the commands of Allah Ta‘ala. However, as far as producing results is concerned, then we should believe and understand that everything happens with the will of Allah Ta‘ala and we do not have control over the outcome. Thus, we will adopt the means, but will place our complete reliance and trust on the assistance of Allah Ta‘ala and will believe that He alone can produce the desired results and bless us with success.
