Is it permissible for a person

Q: What is the ruling on offering Salah (Prayer) behind a blind Imam (the one who leads congregational Prayer) who sometimes makes errors?

(Part No. 7; Page No. 387)  A: Offering congregational Salah behind a blind Imam is permissible. It might even be preferable if he is better at reciting the Qur'an than those who perform the Salah behind him. This is based on the general meaning of what the Prophet (peace be upon him) said, "The best reciter of Allah's Book should lead the people." It was authentically reported that the Prophet (peace be upon him) Appointed Ibn Um Maktum to lead people in Salah, and he was a blind man. (Related by Imam Ahmad and Abu Dawud) As for his mistakes in reciting the Qur'an, here is an explanation of the Fiqh (Islamic jurisprudence) related to it: If his mistakes are related to Lahn (incorrect recitation due to mispronunciation of letters or syntax) that does not change the meaning, performing a Salah behind him will be valid. However, it would be better to follow an Imam who is free from such mistakes. If his Lahn changes the meaning, Salah led by him will be Batil (null and void), because of the Lahn not because of his blindness. An example of a Lahn that changes the meaning is pronouncing the vowel point Fat-hah (vowel point that sounds like "a") as Kasrah (vowel point that sounds like "i") in the word "Iyyaka", which can be translated as "you", as in: You (Alone) we worship [as this will make the pronoun refer to a female instead of a male. Trans.] or pronouncing the Fat-hah as a Dammah (vowel point that sounds like "u") at the end of the word "An`amta", which can be translated as "You have bestowed Your Grace", as in: ...those on whom You have bestowed Your Grace [as this will make it a first person pronoun, whereas it should be a second person pronoun. Trans.]. If the Imam's mistakes are due to poor memorization, appointing another person who has memorized the Qur'an well will be better.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family and his Companions!
