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.
A pluralistic social life indicates that this diversity is not just a natural occurrence; But, if it may be associated with God’s decree, which contains a hint to get to know each other; Not to look for similarities, but to appreciate differences. In this regard, in the context of ahl ilmi, the difference in the concept of the ulama’ is a form of mercy for the people.
The role of the Kitab Kuning is vital, and it is a supporter of the concept of developing a school of thought. Whether we realize it or not, analogy and comparative methods are applied in determining the law, whether state or religious. They are finding common ground then concocting through a long debate.
The orientation is to apply religious law without offending and even changing plural local wisdom, both in the standard law order or national law.
