What is the reason for the dislike of the imamate of those whose imamate is makruh?
Question
[There is the] text: [ar]والأولى بالإمامة الأعلم بالسنة، ثم الأقرأ، ثم الأورع، ثم الأسن، فإن أمَّ عبد أو أعرابي أو فاسق أو أعمى أو مبتدع أو ولد الزنا كُره[/ar] “The most entitled to the imamate is the one most knowledgeable of the sunna, then the best reciter (aqra’), then the most scrupulous (awra‘), then the eldest. If a slave, a Bedouin (a‘rabi), a fasiq, a blind man, a mubtadi‘ (innovator) or one born of zina leads the prayer, it is makruh.
Answer
If this blind man is careful in matters of purity (tahara) and is superior [to the others], his imamate is not makruh: the Messenger of Allah ﷺ appointed Hadrat Ibn Umm Maktum ﵁ as imam in blessed Madina when he set out on a journey. As for the fasiq and the mubtadi‘, even if he is an ‘alim and a qari, his imamate will still be makruh. Concerning the slave, the Bedouin (a‘rabi)
