How can we reconcile the perfection of religion mentioned in the verse, "This day I have perfected for you your religion," with the existence of numerous disagreements among scholars on jurisprudential issues?

There is no contradiction between the perfection of Sharia and the differences among scholars. The perfection of the religion is embodied in its general principles and rules, while specific issues are renewable, and scholars exert effort to incorporate them within those rules.

The differences among scholars stem from varying levels of understanding and knowledge they possess. Some may be unaware of what others know, or they may interpret texts in different ways. This does not contradict the completeness of the religion; rather, it is an attempt to arrive at Allah's ruling in matters for which no definitive text exists.

Thus, the contradiction is not in the Sharia texts themselves, but rather in the view of the mujtahid (independent jurist) and the obscurity or incomplete understanding of the evidence, which affirms the perfection of Sharia and the striving of the mujtahids to ascertain Allah's ruling.
