If you are doing the fard and following the sunnah..Alhamdulillah !!
We think that if we are praying 5 times a day,fasting,doing voluntary salah and fasts,doing good deeds-we think we are pious and we are doing a great job and doing something great,perhaps a favour to Islam,to Allah and His Messenger.
The purpose of our creation is to worship Allah alone.That doesnt mean our worshipping Allah will increase His Glory neither will our not worshipping Him decrease His Glory.
He is the All-Mighty,All-Powerful,The Lord of the Heavens and the Earth,The Lord of the Majestic Throne,The Lord of the Universe.Allah is Great.
Our worshipping Him,striving in His Cause,obeying His Commands,following the Sunnah of His Messenger pbuh..all this is a favour,a privilege HE has bestowed upon us,HE has Guided us,HE made the practising of Deen easy for us.
We sin and He Forgives our shortcomings.
He rewards us tenfold or more for a good deed.
“They consider it a favor to you that they have accepted Islam. Say, “Do not consider your Islam a favor to me. Rather, Allah has conferred favor upon you that He has guided you to the faith, if you should be truthful.”
