I add: that is, it refers to the forthcoming report of Ibn ʿUmar, namely: (1) Malik recorded it in the Muwattaʾ (1/193); al-Bukhari (8/161) transmitted it through his chain; Muhammad [b. al-Hasan] in his Muwattaʾ (p. 155); al-Shafiʿi in al-Umm (1/83); and, through him, al-Bayhaqi (2/8), all from Nafiʿ: Whenever ʿAbd Allah b. ʿUmar was asked about the *salat al-khawf* (prayer in time of danger) he would say, “The imam advances with one group …,” and then he related the remainder of the incident. Ibn ʿUmar added, “If the danger becomes more intense than that, then pray on foot, standing on your feet, or mounted, whether facing the qiblah or not.” Malik said: Nafiʿ remarked, “I do not think ʿAbd Allah b. ʿUmar mentioned this except on the authority of the Messenger of Allah ﷺ.” Ibn Khuzaymah also reported it from Malik without hesitation (Talkhis, 3/209).
