Our duties towards Allah The Creator, is to know that He is The Only God, Who Created us and Showered and Showering on us every bounty and Protected us from every evil and harm. We must always thank Him and use His bounties in the proper way and never in doing wrong. Performing obligatory prayers on time and obeying Allah in each and every act or thought is the sign of the believers in Allah.
‘Fulfilling our duties towards His creation is to help others in every good cause we can and to talk to them in the same way we wish them talk to us, and treat them in the same way we wish them treat us.
Allah States in Quran: Verily, Allah Orders in Justice and Fairness and being good to kinship, and Forbids evil and wrong and injustice. (Sura 16, Verse 90).
Wassalam.
