Some commentators have narrated that; the first eleven verses of the chapter, ``SPIDER'' have been revealed in Medina, and the rest in Mecca. These eleven verses, they say, are about the Muslim Converts who had stayed in Mecca, and were not willing to leave their home and hearth, and emigrate to Medina.

      They received a letter from their Muslim brothers, who had emigrated to Medina; that Allah will not accept their faith unless they had emigrated and joined them in Medina.

      So the Meccans decided to emigrate; and when they set out and made for Medina, they were attacked by the pagan idolaters, by which some were slayed, some badly injured, and some could flee to Medina.

      Some commentators have known the second verse above, to have been revealed on the persecution of Ammar and his parent who were martyred in that sad event. Anyhow, in its general sense of meaning, the above verses will encourage Muslims to be patient, and stay firm against the waves of enmity and persecutions to which they were confronted.

      The connections and continuities of the said eleven verses are reasons, through which we believe they have all been revealed in Mecca.
