I just wanna clear that the statement said in the movie "not praying before eating is a sin " is 100% wrong and many more things
It is better to pray and it's just a sentence " Bismillah-ir-Rehman-ir-Rahim" meaning " Shru krta hoon main Allah k nam se "
Is anything wrong in it ??
So ...don't misguide people
And you can't !
