Islam is a complete and perfect religion. To maintain the perfection and finality of shari'ah, Islamic shari'ah must be able to respond to problems and developments in human life and civilization that are increasingly dynamic. An increasingly advanced human civilization demands many challenges faced by the shari'ah. Events that took place in the early era of the birth of Islam, or phenomena that occurred in the classical period and had been formulated by scholars, could be reviewed, or new cases emerged with new, more complicated dynamics, and no legal answers were found. For example, clothes or bodies stained with young boys' urine, marrying a mother or sister, online Friday prayers, and virtual Hajj in the Metaverse Virtual World. The scholars, since time immemorial, have been polarized on several manhaj and established Islamic law, namely the first group, which in determining the dominant law uses reason, and the second group, which is too fixated on what is contained in the syar'i text (Al-Qur'an – Hadith). The working pattern of these two understandings presents a challenge that is not simple because, from these two patterns, it is hoped that Islamic law must still appear as a law that is righteous and lawful during the time of eating.
