تفسير القرآن العظيم:تفسير ابن كثير-العلمية

This is probably the most famous tafsir work, famous for the author sifting out the views of the various mufassirin before him and relying on the strongest view, as well as being one of the few tafasir wherein the author mentions the strength of most of the narrations he brings, generally staying away from very weak narrations.
