—may Allah bless him and grant him peace. They said (1): The term khalīfa (successor) applies only to someone appointed as successor by another. They understood the fa‘īl pattern here in the sense of a passive participle. This therefore showed that the Prophet—may Allah bless him and grant him peace—had designated (2) a successor over his community.
Those who disputed this argument replied: The term khalīfa applies both to someone whom another has appointed as successor and to someone who succeeds another. In the latter usage, the fa‘īl pattern carries the sense of an active participle, as when one says, “So-and-so succeeded so-and-so.” Similarly, the Prophet—may Allah bless him and grant him peace—said in the two Sahīh collections (3):
“Whoever equips a fighter has thereby taken part in the campaign, and whoever takes good care of his family in his absence has thereby taken part in the campaign.” (4)
And in another hadith:
“O Allah, You are the Companion on the journey and the One who watches over the family in our absence. O Allah, accompany us on our journey and watch over our family in our absence.” (5)
(1) N and M read: “He said.”
(2) N and M read: “He appointed him as successor.”
(3) A and B read: “in an authentic hadith.”
(4) The hadith is narrated from Zayd ibn Khālid—may Allah be pleased with him—in *Sahīh al-Bukhārī*, 4/27 (*Book of Jihad*, chapter “The Merit of Equipping a Fighter”); *Sahīh Muslim*, 3/1506–1507 (*Book of Governance*, chapter “The Merit of Assisting a Fighter…”); *Sunan Abī Dāwūd*, 3/18 (*Book of Jihad*, chapter “Reports Concerning One Who Equips a Fighter”); and *al-Musnad* (al-Halabī ed.), 4/115–117 and 5/193.
(5) A and B read: “our families.” The hadith in this wording forms the first part of a hadith narrated from Abd Allāh ibn Sarjis—may Allah be pleased with him—in *Sunan al-Tirmidhī*, 5/161 (*Book of Supplications*, chapter “What One Says When Setting Out on a Journey”). Al-Tirmidhī said: “This is a sound and authentic hadith.” It also forms part of another hadith narrated from Abd Allāh ibn Umar—may Allah be pleased with him—in *Sunan al-Tirmidhī*, 5/165 (*Book of Supplications*, chapter “What One Says When Mounting a Riding Animal”). The hadith begins: Ibn Umar reported that when the Prophet—may Allah bless him and grant him peace—set out on a journey and mounted his riding animal, he would proclaim Allah’s greatness three times and say: “Glory be to Him who has subjected this to us, though we could never have mastered it, and surely to our Lord we shall return.” He would then say: “O Allah, I ask You during this journey of mine…” to the end of the hadith. Al-Tirmidhī said: “This is a sound hadith.” This latter hadith is also found in *al-Musnad* (al-Ma‘ārif ed.), 9/138–139.
The first of these phrases—namely, the Prophet’s words, “O Allah, You are the Companion on the journey and the One who watches over the family in our absence”—appears in many hadiths. These include a hadith narrated from Ibn Umar in *Sahīh Muslim*, 2/978 (*Book of Hajj*, chapter “What One Says When Mounting for a Journey of Hajj or Otherwise”), and *al-Musnad* (al-Ma‘ārif ed.), 9/185; a hadith narrated from Abū Hurayra in *Sunan al-Tirmidhī*, 5/160 (*Book of Supplications*, chapter “What One Says When Setting Out on a Journey”), and *al-Musnad* (al-Ma‘ārif ed.), 18/21–22, and (al-Halabī ed.), 2/433; and a hadith narrated from Ibn Abbās in Ahmad’s *Musnad* (al-Ma‘ārif ed.), 4/87 and 255.
