A booklet on the Hijra and its obligation, written by a professor specialized in the Quran and Tafseer, which makes thorough an exegesis of the famous verse in Surah al-Nisaa on Hijrah:

(Indeed, those whom the angels take [in death] while wronging themselves - [the angels] will say, "In what [condition] were you?" They will say, "We were oppressed in the land." The angels will say, "Was not the earth of Allah spacious [enough] for you to emigrate therein?" For those, their refuge is Hell - and evil it is as a destination.) An-Nisa.! 97.

The author explains the context of the revelation, explains all terms of the verse and goes all the benefits and rules that may have drawn from this noble verse (43 Fawaid and Ahkaam).
