Qath'i and zhanni in Usul fiqh are useful to explain the source text of Islāmic law, both the Qur'an
and the hadith in two ways, namely al-tsubut (existence) or al-wurud (coming of the truth of the source)
and al-dalalah (interpretation). In the context of qath'i and zhanny al-wurud the scholars agree that alQur'an and muthatith hadith are qath’y.. But they differ in terms of qath'i and zhanni from aldalalah's side. The ulama of ushul fiqh states that there are religious texts that only contain one clear
meaning and cannot debate other interpretations, also contain certain numbers, so the text is considered
as a qath'i al-dalalah text. While contemporary scholars argue that the concept of qath'i
and zhanni While contemporary scholars argue that the concept of qath'i and zhanni al-dalalah both
the Qur'an and Hadith cannot be seen from the meaning of lafaz alone but also on the desired essence
of the lafaz. Thus, the result is that religious texts in the field of inheritance law are open to modern
interpretations. Islāmic inheritance include in the Zhanni al-dalalah group because relates to human
relations and socio-economic roles, also, historically the verses on inheritance contain the essential
meaning of justice.
