Quran Chapter 2 Verse 169-172
And when it is said to them, “Follow what Allah has revealed,” they say, “Rather, we will follow that which we found our fathers doing.” Even though their fathers understood nothing, nor were they guided?
The example of those who disbelieve is like that of one who shouts at what hears nothing but calls and cries cattle or sheep – deaf, dumb and blind, so they do not understand.
O you who have believed, eat from the good things which We have provided for you and be grateful to Allah if it is [indeed] Him that you worship.
