This tafsir is a compilation of the sayings of the Imams about the surahs and individuals ayahs based on the teachings of our beloved Prophet Muhammed (saw) to his family.
The interpretation by the Imams is weighty and their imaan is pure because Allah has mentioned them as follows in the Quran:
innamaa yureedul laahu liyuzhiba 'ankumur rijsa Ahlal Bayti
wa yutahhirakum tatheeraa
Allah wishes only to remove from you evil deeds, O family of the Prophet and to purify you perfectly.
33 Surah Ahzab , 33
