Ibn al-Musayyib said:When the first civil strife occurred, i.e., the assassination of `Uthman, not one of those who had been at Badr remained; when the second occurred, i.e., the Harra, not one of those who had been at al-Hudaibiya remained; and the third [1] one occurred and did not disappear while there was intelligence among the people. [2] 1. Probably a reference to 'Abdallah b. az-Zubair who claimed the Caliphate and was killed in 73 A.H. when al-Hajjaj stormed Mecca. 2. See Bukhari, Maghazi, 12, where the wording is slightly different. Qastallani remarks that tabakh means `intelligence,' but some say 'strength' and also `remains of good in the religion'. I have used the meaning he prefers, but one might use 'strength' which is said to be the basic meaning. Lane gives 'firmness,' 'soundness,' `strength and fatness', 'intelligence' and `good,' Cf. Mirqat. v, 153. Bukhari transmitted it.
