What is the difference between the Fiqh of Sunnah and the Fiqh of Seerah, and are there other types of Fiqh?

The Prophet's biography (peace and blessings be upon him) is part of his Sunnah. Imam Al-Bukhari included his biography and campaigns in his Sahih. Some scholars have written books on the Sirah, calling them "Fiqh As-Sirah" (Jurisprudence of the Biography), such as the books by Al-Ghazali and Al-Bouti. These books narrate events from the Sirah and derive lessons, morals, and jurisprudential rulings from them. In conclusion, books of Fiqh As-Sirah deal with the Prophet's biography to deduce lessons and rulings, while books of Fiqh As-Sunnah address jurisprudential issues and their associated hadiths and are not specifically dedicated to the Sirah.
