Growing a beard is one of the recommended acts in Islam and is a great Sunnah of the Prophet (peace and blessings be upon him). On growing a beard, a Muslim should be keen to maintain good appearance and to set a good example in his commitment to his religion as well as leading a successful life.
Sheikh Mohamed El-Moctar El-Shinqiti, Director of the Islamic Center of South Plains, Lubbock, Texas, states: According to many contemporary scholars, growing the beard is not wajib, but it is one of the recommended acts or the ‘outward appearance’ as Imam IbnTaymiyah calls it, which is not related to the essential elements of the deen and its fundamental principles. Therefore, there is no need to make it a point of contention between families. Moreover, sons in this position should explain to their fathers that they’re only practicing the Sunnah of the prophet SAW.
