Allah (SWT) sent His final messenger, Prophet Muhammad (PBUH), as a source of knowledge for the entire ummah. He was the fountain of Quran, Hadith, tafsir, rhetoric, fiqh, and so on. After the Prophet (PBUH), the scholars of this ummah carried and propagated each of these branches of knowledge. Because no one person can attain the perfection of the Prophet (PBUH), who single handedly assumed all o
f these roles, various branches of the Islamic sciences developed. For example, Imam Abu Hanifah preserved the science of fiqh and after him thousands of scholars continued in his footsteps. Hence these scholars preserved the fiqh of the Prophet (PBUH). Similarly Imam Bukhari and the other famous scholars of Hadith, preserved the words of the Prophet. The scholars of tajweed preserved the recitation of the Prophet (PBUH). And, the scholars of Arabic grammar preserved the language of the Prophet (PBUH).
