The first and foremost exegesis / tafsir of the Qur'an is found in hadith of prophet Muhammad. Although scholars including ibn Taymiyyah claim that Muhammad (s) has commented on the whole of the Qur'an , others including Ghazali cite the limited amount of narratives, thus indicating that he has commented only on a portion of the Qur'an . Hadith / Hadis (حديث) is literally "speech" or "report", that is a recorded saying or tradition of Muhammad (s) validated by isnad; with Sirah Rasul Allah these comprise the sunnah and reveal shariah. According to Hazrat Aishah (r.a), the life of Prophet Muhammad (s) was practical implementation of Qur'an. Therefore, mention in hadith elevates the importance of the pertinent surah from a certain perspective.
