I forgot that I did not have wudoo’ and I prayed. After I finished my prayer, I remembered that. Do I have to repeat my prayer?
Praise be to Allaah.
Yes, whoever prays forgetting
that he does not have wudoo’ has to repeat the prayer, because the Messenger
(peace and blessings of Allaah
be upon him) said: “Allaah does not accept any prayer if a person breaks
his wudoo’, until he does wudoo’.” (Narrated by al-Bukhaari from the
hadeeth of Abu Hurayrah (may Allaah be pleased with him) in Kitaab
al-Wudoo’. This is in contrast to the person who has some impurity
(najaasah) on his clothes and he forgets it. He does not have to repeat
his prayer because Jibreel came to the Prophet
(peace and blessings of Allaah be upon him) whilst he was praying, and
told him that there was something dirty on his shoes. He took them off
and continued praying. This was narrated by Ahmad from the hadeeth of
Abu Sa’eed al-Khudri (may Allaah be pleased with him) in his Musnad.
This hadeeth proves that the one who is unaware of the najaasah
does not have to repeat his prayer, and this applies also to the one
who forgets that there is some najaasah present.
