(1) *Sahīh al-Bukhārī*, Book of Heart-Softening Narrations, chapter “The Prophet’s Statement: ‘I and the Hour were sent like these two,’” narrated by Sahl (may Allah be pleased with him), 11/347, with *Fath al-Bārī*. (2) Al-Albānī said: “It was narrated by al-Dūlābī in *al-Kunā* (1/23) and Ibn Manda in *al-Marifa* (2/234/2), through Abū Hāzim, from Abū Jubayra, who attributed it directly to the Prophet. Its chain of transmission is authentic, and all its narrators are trustworthy. There is disagreement over whether Abū Jubayra was a Companion, but al-Hāfiz Ibn Hajar concluded in *al-Taqrīb* that he was.” *Silsilat al-Ahādīth al-Sahīha*, 2/467, hadith 808. See also: *Tahdhīb al-Tahdhīb*, 12/52–53, section on teknonyms, Dāirat al-Maārif Council Press, India, 1st ed., 1327 AH; and *Taqrīb al-Tahdhīb*, 2/405, edited by Abd al-Wahhāb Abd al-Latīf, Dār al-Marifa, 2nd ed., 1395 AH.

(4) *Quayqiān*—with a *u* after the first *q* and an *i* after the second, following the diminutive form—is a mountain about twelve miles south of Mecca. It was named Quayqiān because, when Jurhum fought among themselves, the clatter of weapons there was intense. It appears that the Prophet, peace and blessings be upon him, made this statement either during the Farewell Pilgrimage or during the Conquest of Mecca; Ibn Umar attended both alongside the Companions. See: Ibn al-Athīr, *al-Nihāya*, 4/88; and Ahmad Shākir, *Sharh Musnad Ahmad*, 8/176.
