Salim quoted his father (Abdullah bin Umar) who reported God's messenger as saying. 'The breadth of the gate by which my people will enter paradise will be a three years[*] journey for a fine rider, yet they will be so crushed that they will almost lose their shoulders." *The noun le not specified in the text. From the form of the numeral, it might be either nights or years. Mirqat 5, 207. expresses a preference for years, as that conveys better the idea of huge extent. Tirmidhi transmitted it, saying that this is a weak tradition, and that when he asked Muhammad b. Ismail about this tradition he did not know it, adding that Yakhlud b.Abu Bakr transmitted dis acknowledged traditions.
