Fatwa number ( 16721 )
Q: A man prayed 'Asr three rak'ahs and then remembered after a day Should he make it up or repeat it?
A: It is obligatory for him to repeat the prayer with four rak'ahs; because the prayer he performed is not valid. And success is from Allah, and may Allah send prayers and blessings upon our Prophet Muhammad, his family, and his Companions.
