Hadrat Ibn-e-‘Umar Radi ALLAHu Ta'ala Anho reported that the Messenger of Allah has said, “Do the opposite of what the polytheists do; let the beard grow long and clip the mustache.” A version has, “trim the mustache down and leave the beard.” [Sahih Bukhari, Vol 2, Page 875]
Hadrat Zaid ibn Arqam Radi ALLAHu Ta'ala Anho reported that the Messenger of Allah has said, “Whoever does not take something off his mustache is not one of us (not on our path).” [Sunan Nisa'i, Vol 2, Page 274]
