This the famous Urdu tafseer of Quran by Abul Ala Maududi also known as "Tafhimu'l-Qur'an". It introduces the four interrelated concepts that Maududi believed essential to understanding the Quran: ilah (divinity), rabb (lord), ibadah (worship, meaning not the cherishing or praising of God but acting out absolute obedience to Him), and din (religion). It is really helpful when you are listening to Quran translation and want to exactly understand the context of sayings.
