Repentance
[9:101]
But among the bedouin who dwell around you there are hypocrites; and among the people of the [Prophet’s] City [too] there are such as have grown insolent in [their] hypocrisy. Thou dost not [always] know them, [O Muhammad – but] We know them. We shall cause them to suffer doubly [in this world]; and then they will be given over to awesome suffering [in the life to come].


* v.101 : I.e., Medina. Originally, the city bore the name Yathrib; but after the exodus of the Prophet from Mecca it came to be known as Madīnat an-Nabī (“the City of the Prophet”) and, eventually, as Al-Madīnah (“The City” par excellence).
* I.e., first through failure in their worldly concerns, accompanied by pangs of conscience and the resulting spiritual distress, and then through a full realization, at the moment of dying, of the unforgivable nature of their sin (Manār XI, 19).
