Superiority in lineage
Q:
1. My question is regarding the rule in Islam that commands Muslims to choose their caliph (khalifah) from among the tribe of Quraysh. The question here rises that how can Islam limit leadership to Quraysh and create a concept of Qurayshi , Non-Qurayshi.
2. Secondly I have read on another website that Arab Muslims who's piety is superior to non Arab Muslims piety in “general terms” as they are better in linage and descent. This again is a very irrational mentality. Clarify the following.
