2. Favoring one opinion in a particular Madhab over the other in the same Madhab, this is known as

Tarjeeh. In every Madhab there would be differences of opinions. The scholars would look at their madhab and determine which opinion should be the final opinion of the Madhab based on the Usools derived from their study of other rules. This resulted in much infighting in the Madhahib. It was necessary to define the terms used in a Madhab so that everyone came understand what is meant when a specific word of phrase is used. There were many differences between the Madhahib in the definition of certain terms and phrases. The most common example is the definition of Wajib. The Hanafi Madhab defines it as an act in which there is a difference of opinion from the scholars as to if it is Fard or not, like Witr. The other Madhahib define Wajid as the same as Fard. Other terms used were Ashaabuna, referring to the followers of the Madhab and Riwaayah, referring to the statements of the Imam of their Madhab.
