This booklet is derived from a thesis paper deliverd by Mufti Muhammad Shafi in Dhul Qadah 1385 A.H. in Lyllpur, Pakistan. The Mulim Ummah is an undividable unit but present conditions do not reflect that. Islam invites towards unity and encourages all Muslims, in fact the whole humanity to be one nation, one family and one brotherhood. The esteem author discusses the positive aspect of Muslim unity in more detail the negative aspect and its causes and cure.
