The importance of traditional and contemporary Islamic Jurisprudence (fiqh) is well known. Fiqh deals with all aspects relating to a believer's life. The Messenger of Allah (Allah bless him & give him peace) said:
"He for whom Allah desires great good, He grants him (superlative) understanding in the Religion. I only distribute and it is Allah Who gives. That group shall remain in charge of the Order of Allah, unharmed by those who oppose them, until the coming of the Order of Allah." (Sahih al-Bukhari)
Imam Abu Hanifa (Allah be pleased with him) said, "Fiqh is to know what is for and against oneself."
