 tell them act as you wish. god his messenger and the believers will see your deeds. you will be brought before the one who has absolute knowledge of the unseen and the seen. he will let you know about all that you have done.
وقل اعملوا فسيرى الله عملكم ورسوله والمؤمنون وستردون إلى عالم الغيب والشهادة فينبئكم بما كنتم تعملون
