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. 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 Prophet Muhammad was practical implementation of Qur'an. Therefore, mention in hadith elevates the importance of the pertinent surah from a certain perspective. Ibn Abbas is known for his knowledge of traditions as well as his critical interpretation of the Qur'an. From early on, he gathered information from other companions of Muhammad and gave classes and wrote commentaries. According to him "When the Prophet Muhammad came to Al-Madinah, they were the worst people in weights and measures. Then, Allah, Glorious is He revealed: "Woe to the Mutaffifun (those who give less in measure and weight)"(Al-Mutaffifin), and they were fair in weights and measures after that. According to Abdullah ibn Masud, Muhammad used to recite two equal surahs in one rak'ah; he would recite (for instance) An-Naziat (79) in one rak'ah, surahs (Al-Mutaffifin) (83) and Sūrat al-ʿAbasa (80) in one rak'ah.
