Sister Helena i agree with you totally, many of the Muslims have taken these nasheed singers as role models instead of the Prophet(pbuh). So we must speak out and educate those people about the correct path of the Quran and Sunnah. Among the Majority of the ulema of the Salaf they agree the beard is Wajib and that shaving it is haram, they even go as far as saing that the person who shaves his beard his testimony will not be accepted and that he can not lead the Salah.
According to the Hanafis it is prohibited to shave the beard (Ad-Durh al Muktahr)
According to the Malakiis it is prohibited to shave the beeard (Sharh ur-Risalah)
According to the Shafiis it is prohibited to shave the beard unless you have a medical reason(Sharh al ubab)
According to the Hanbalis, Ibn Taymiyyah says it is prohibited to shave the beard (Al- Ikhtiyarat)
so from this it is quite clear that the Scholars of the Salaf agree that it is prohibited to trim the beard let alone to design in a way imitates the non believers.
The command of the Prohet(pbuh) are clear that you should leave the beards to grow, there is no authentic narration to sugeest that the Prohet or the comapnions ever shavedthere beards. However there are narrations from Ibn Umar, Ibn Abbass that whatever extended below the fist lenth would be trimmed "Abdullah Ibn Umar went for Hajj he used to hold his beard and cut what ever extended below his fist" (Bukhari)
There are many hadiths where Prophet(pbuh) told us to spare our beards and not to imiate the kuffar "closely trim the moustaches and spare the beards" (Bukhari) "cut the moustaches and grow your beards. Be different from the magians" (Muslim)
so brothers we can clearly see that the beard is something we can not take lightley, we must advice, educate, our brothers about this issue and give naseeah that the Prophet(pbuh) way is the right way, and highlight that other than is the hellfire.
