1) Is it permissible for a person who is clean shaven (due to medical reasons – acne) to be Imaam of salaah?
2) If yes, would it still be permissible when they are Ulemaa and Huffaaz who would meet all requirements of an Imaam?
1) That person should not make Imaamat. Let him be treated medically. May Allaah grant him total cure. Then when he grows a full fledged Shaari beard, he may be allowed to lead the Salaat.
