Beards and Moustache

Using beard growing oil

Q: My question is regarding beard transplantation. I’m almost 26, I don’t have a beard on my face, just a little under my chin. I have desire to grow a beard and In Sha Allah grow a healthy beard according to the sunnah in the next few years. Is it allowed to go for a beard transplantation or use any beard growing oil on face? Will it be against the creation of Allah?

Keeping a beard more than a fist length

Q: My question is regarding cutting beard when it reaches length of one fist.

I have noticed there are scholars who say one should leave the beard and not cut it at all because there is no proper evidence. They say that the hadith of Umar (radhiyallahu anhu) tells about cutting the beard during hajj or umrah only. So that means that we cannot cut the beard during any other time. They also say that according to one hadith narrated by Abu Hurairah (radhiyallahu anhu), Nabi Muhammad (sallallahu alaihi wasallam) said to cut the beard and leave the beard, i.e. don't touch the beard.

While there are scholars who say that Imam Ahmed (rahimahullah) used to cut the beard when it reached the length of one fist and also gives proof of other righteous predecessors. So, is there any evidence that Umar (radhiyallahu anhu) used to cut his beard other than hajj or umrah and other Taabioon or 4 great Imaams did it?
