Tirmidhi

1؎ : The evidence of these people for the chapter is this very hadith, but deducing from this hadith depends on two points: First, that the wording in the hadith should be as follows «قاء فتوضأ» "He vomited, so he performed ablution," whereas this wording is not preserved. In most sources of hadith, in the narrations of most transmitters, it is «قاء فأفطر» "He vomited, so he broke his fast" «فأفطر» and even after that, there is no wording of «فتوضأ», or it is as it is in this narration, that is «قاء فأفطرفتوضأ» "That is, he vomited, so he broke his fast, and after that performed ablution." And from this wording, the obligation of ablution (wudu) is not established, because it happens that after vomiting, a person becomes weak, so he breaks his fast, and for cleanliness performs ablution, and the Messenger of Allah (sallallahu alayhi wa sallam) was even more fond of cleanliness. Also, this was merely an action of the Prophet (sallallahu alayhi wa sallam) without any accompanying command from him. Second, if the wording of «قاء فتوضأ» is indeed preserved, then the "fa" (ف) of «فتوضأ» could be for causation, meaning: "He vomited, so he performed ablution because of it." But this is not definite; rather, this "fa" could also be for sequence, meaning: "He vomited, and after that performed ablution."

2؎ : The evidence of these people is that narration of Jabir (radi Allahu anhu) which Imam Bukhari has mentioned in suspended form (ta'liq), that the Prophet (sallallahu alayhi wa sallam) was in the expedition of Dhat al-Riqa', when an arrow struck a man and blood began to flow, but he continued his prayer and kept performing bowing (ruku') and prostration (sujud) in that state. It is evident that the Prophet (sallallahu alayhi wa sallam) must certainly have known about this prayer of his, because this prayer was performed while on guard duty, which the Prophet (sallallahu alayhi wa sallam) had ordered him to do. Despite this, the Prophet (sallallahu alayhi wa sallam) did not command him to perform ablution or to repeat the prayer.
