The months of performing the Hajj are well Known; so whoever undertakes to perform the Hajj in them (should remember that) there is (to be) no obscenity, nor abusing, nor any wrangling during the (time of) Hajj. And whatever good you do Allâh knows it. And take provisions for yourselves. Surely, the good of taking provision is guarding (yourselves) against the evil (of committing sin and begging). Take Me alone as (your) shield, O people of pure and clear wisdom! - Quran 2:197
