The things nullifying the ablution:
- Whatever comes out of the stool and urine exits, such as stool wind, urine, sperm, pre-seminal fluid, and unusual menstrual blood. Stool and urine are among the direct things nullifying ablution, as when Allaah, Exalted be He, revealed the cases that obligate ablution He said: “Or one of you comes from the place of relieving himself…” (Al-Maida: 6)
As for sperm and pre-seminal fluid, they nullify ablution according to the authentic hadiths reported by Ibnul-Mundhir and Al-Awsat [1/134].
Regarding istihadah (vaginal bleeding other than menstruation), it nullifies ablution according to the hadith reported by Fatimah Bint Abu Hubaysh mentioning that she was afflicted with istihadah, and when she asked the Prophet Sallallaahu Alayhi Wa Sallam about its ruling, the Prophet Sallallaahu Alayhi Wa Sallam said: “Perform ablution and then (you can) offer prayer, for it is (due only to) a vein”.
Breaking wind also nullifies ablution, as the Prophet Sallallaahu Alayhi Wa Sallam said: “Allaah will not accept the prayer of anyone of you if he passes urine, stool or breaks wind until he performs ablution”.
Also, The Messenger of Allaah (Sallallaahu Alayhi Wa Sallam) said regarding one’s uncertainty whether one had broken wind or not: “One should not leave prayer (to re-perform ablution) unless one hears sound (of breaking wind) or smells something.” (Al-Bukhari (137) [1/312] and Muslim (802)[2/272]).
- Mental unconsciousness either due to insanity or due to sleeping, fainting and the like. Thus, the ablution of one in such a state is deemed null, as there is suspicion in this case that something has come out of one’s body while one is unaware.
Light sleep however, does not break ablution, as the Prophet’s companions (May Allaah be pleased with them) used to doze while waiting for prayer at the mosque. (Muslim (833) [2/296])
- Eating meat of camels, according to the authentic hadith of Allaah’s Messenger Sallallaahu Alayhi Wa Sallam in this regard (Muslim (800)[1/271]).
