Hadith
The first and foremost exegesis/tafsir of the Quran is found in hadith of Muhammad. Although scholars including ibn Taymiyyah claim that Muhammad has commented on the whole of the Quran, others including Ghazali cite the limited amount of narratives, thus indicating that he has commented only on a portion of the Quran. Ḥadīth (حديث) is literally "speech" or "report", that is a recorded saying or tradition of Muhammad validated by isnad; with Sirah Rasul Allah these comprise the sunnah and reveal shariah. According to Aishah, the life of Muhammad was practical implementation of the Quran. Therefore, mention in hadith elevates the importance of the pertinent surah from a certain perspective. According to hadith, Muhammad used to recite this surah in Zuhr prayer and Asr prayer. Jabir bin Samurah narrated: "For Zuhr and Asr, Allah's Messenger would recite: By the heavens, holding the Buruj (Surah 85) and (By the heavens and At-Tariq) and similar to them." References
