As Salamu Alaikum Wa Rahmatullahi wa Barakatuhu
Worship is for Our Own Sake
وَمَن جَاهَدَ فَإِنَّمَا يُجَاهِدُ لِنَفْسِهِ ۚ إِنَّ اللَّهَ لَغَنِيٌّ عَنِ الْعَالَمِينَ
“And whoever strives, he strives for his own sake, for indeed Allah is not in need of anything in this universe.”
(Surah Al-Ankabut 29:6)
In this verse, Allah is reminding us that He is not in need of our worship. Allah is Al-Ghani (The independent, free from all needs) and whether we choose to worship Him or not has no impact on His Greatness.
Rather, Allah reminds us here that our worship and efforts to please Allah are for our own benefit. Everything that Allah has prescribed for us is beneficial for us and everything that Allah has prohibited is harmful to us. Thus by striving to worship Allah, we are doing what is best for ourselves and if we choose to ignore our purpose in life, we only harm ourselves.
Also note that the verb Jaahada in this verse refers to Jihad of the Nafs or striving to practice Islam and does not refer to the physical Jihad.
That is an important point to note as many have a misconception that the word Jihad in the Qur’an always refers to physical warfare. This is incorrect as there are verses were it refers to Jihad of the Nafs, Dawah and speaking the truth as well.
