Would you please let us know the ruling of dying black color to hair / beard ?
I think I heard somewhere that for Men its not allowed. But if your Imam itself leading taraweeh / prayers what should be done ?
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
The Imamah (Leading of Salah) of a Faasiq is Makruh Tahrimi (severely disliked).
Hence, you should make an effort to perform Salah in another Masjid. However, if another Masjid in not easily accessible, then you should perform Salah behind the one who dyes his hair black instead of praying individually. In this case, you will not be sinful and the sin will be on those who appointed the Imam.
Note: The use of dark brown dye is permissible. Only the use of black dye is impermissible.
And Allah Ta’āla Knows Best
