Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

 

Discharging blood does not invalidate ablution according to the Shafi`i and Maliki scholars. This is the most preferred view. It is based on a number of evidences:

 

According to Sunan Abu Dawood, Jabir (may Allah be pleased with him) said: We went out with the Messenger of Allah (peace and blessings of Allah be upon him) on the campaign of Dhaat al-Riqaa`. The Messenger of Allah (peace and blessings of Allah be upon him) said: “Who will guard us?” A man from among the Muhajireen and a man from among the Ansar volunteered. He said: Stand at the mouth of the mountain pass. When the two men went out to the mouth of the mountain pass, the Muhajir lay down and the Ansari stood and prayed. A mushrik man came and shot him with an arrow and struck him, and he pulled it out, until he had shot him with three arrows. Then he bowed and prostrated, then his companion woke up. When the Muhajir saw the blood on him, he said: Subhan Allah, why didn’t you wake me the first time he shot you? He said: I was in the middle of reciting a surah and I did not want to interrupt it. This story came to the Prophet’s knowledge without commenting on it. It means that he has tacitly approved the situation. This is recorded by Imam Nawawi.

 

Moreover, Imam al-Bukhari (may Allah have mercy on him) maintained that Muslims used to pray in their wounds during the times of battles. Similarly, Tawus, Muhammad ibn `Ali, `Ata’ and the people of the Hijaz said: Blood does not affect wudu’. Ibn `Umar has reported as squeezing a pimple and blood came out of it, and he did not do wudu’.

 

Based on all those reports, blood does not break one’s ablution.

 

Allah Almighty knows best.
