In Mecca there are clear signs [of the Lord’s will to keep this cite as the center of His worship.] You will find there a spot where Abraham used to worship. God has made Mecca a sanctuary; whoever enters there, will find safety and security (even during the dark ages of ignorance no body dared to disturb the peace of Mecca and any attack was dismantled even before being started.) Know that it is your obligation to God to visit this place for His worship, if you have the economic mean to travel there. The one who disobeys this commandment should know that God is self sufficient and not in need of anybody’s obedience [and disobedience of God is the person’s loss.]
