New knowledge will inevitably determine dialectical attitudes in social and religious life where there are various istinbath processes, leaving various fanaticism and one-sided truths. Determining one truth requires different truth arguments about that truth.
If a child throws wood at his parents, then it hits his leg and bruises it, is the child said to be guilty? Then there will be various aspects of the legal basis used to look at the case; in other words, do not take a hasty attitude.
Various legal attitudes colour religious life and are characterized by the practice of multiple schools of thought. Islam itself has four well-known schools in carrying out religious law: Maliki, Hanbali, Shafii, and Hanafi. With the Aswaja approach (ahl al-sunnah wa al-jama’ah) as a method of thinking and moving (manhaj al-fikr wa al-harakah), in this case, the reference is turats or the yellow book or Kitab Kuning.
Nahdlatul Ulama or NU has two views regarding applying sharia law, being authoritative and considering the benefit. First, Islam has the authority to regulate the lives of religious people; Second, Islam also keeps anyone outside of Islam running and maintaining a pluralistic relationship.
Kitab Kuning has various styles and backgrounds of discussion because of its diverse knowledge content. So, it is natural that NU in the Bahtsul Masa’il majlis is still dominant in using the yellow book as a reference to complete the legal basis of the Qur’an and sunnah. It is also natural when the students maintain the sacredness of the yellow book while maintaining the Qur’an and the books of hadith. The closeness between NU and pesantren underlies that historically NU was born from the granary of pesantren, where pesantren is required by turats culture.
