Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) once mentioned:
The science of Fiqh (jurisprudence) is an extremely difficult science. There is a need for those issuing fatwas (Islamic rulings) to exercise caution when issuing fatwas. Most of the time, we find that people are lax in masaa’il and follow whatever they desire. This aspect is especially evident among the ghair-muqallideen (those who do not commit themselves to the following of a mazhab). (Malfoozaat Hakeemul Ummat 6/202)
