ummah was no longer a homogenous group but various cultural communities with their own age-old customs and traditions. ... When Imam Al-Shafi‘i moved from Hejaz to Egypt, which was a confluence of Arab and Coptic cultures, he realised this and changed his position on several issues. In Indonesia, following considerable debate among the ulema, Indonesian "adaat" "become part of Sharia as applicable in that country". This use of ijtihad to apply "adaat" applies to "mu’amalat" (socio-economic matters such as marriage, divorce, inheritance), rather than "Ibadah" fiqh (ritual salat, sawm, zakat, etc.). Asghar Ali Engineer argues that while the Arab "adaat" the Quran was revealed in was "highly patriarchal" and still informs what is understood as sharia, the "transcendental Quranic vision" is for "absolutely equal rights" between genders and should guide ijtihad of sharia.
