Does blood flowing from the body invalidate ablution?

The discharge of impurities from the body occurs in three situations:

1. Urine or feces from the usual exit: This nullifies ablution by consensus, due to Allah's saying: (And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and find no water, then seek pure earth and wipe over your faces and hands with it) [Quran 5:6], and the hadith of Safwan ibn Assal regarding the Prophet's command to remove the khuff (leather slippers) for feces, urine, and sleep.

2. Urine or feces from an unusual exit: This also nullifies ablution, because the evidence encompasses the general discharge of both, whether from the usual or unusual exit.

3. Impurities other than urine and feces (such as blood and vomit): Scholars differ on this: The view that it nullifies ablution: They cited the hadith of the woman with irregular bleeding (mustahadah): (That is only a vein, so perform ablution for every prayer), and the hadith of Abu Darda' that the Prophet vomited and then performed ablution. The view that it does not nullify ablution (which is the preponderant view): The default is that ablution is not nullified unless there is sound evidence. They responded to the hadith of the mustahadah by explaining that its meaning is to negate it being menstrual blood, not that every blood discharge necessitates ablution. They responded to the hadith of Abu Darda' by deeming it weak, and even if it were authentic, it is an action that does not indicate the obligation of ablution but rather its desirability.
