I. Hadrat Sayyiduna Ibn ‘Umar (Radi Allahu Ta’ala Anhu) reported that the Messenger of Allah (SallAllahu Alayhi wa Sallam) 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, Hadith 781]

II. Hadrat Zayd ibn Arqam (Radi Allahu Ta’ala Anhu) reported that the Messenger of Allah (SallAllahu Alayhi wa Sallam) 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]

III. Sayyiduna Abu Hurayra (Radi Allahu Ta’ala Anhu) reported that the Holy Prophet (Peace and Blessings be Upon Him) said: “He who does not shave off the hair from the abdomen and does not cut his nails and does not trim his mustaches is not of us”.

IV. Sayyiduna Anas (Radi Allahu Ta’ala Anhu) reported that the Messenger of Allah (SallAllahu Alayhi wa Sallam) said: “The maximum exemption for shaving off the hair from the abdomen and armpit and for cutting nails and for trimming the mustaches is forty days.” [Sahih Muslim, Vol. 2, Page 128, Hadith 497]

V. Hadrat Abu Huraira (Radi Allahu Ta’ala Anhu) reported that the Messenger of Allah (SallAllahu Alayhi wa Sallam) has said, “Cut the mustaches and let the beards grow long; (by doing this) do the opposite of the fire worshipers.” [Sahih Muslim, Vol. 2, Page 129, Hadith 501]

VI. Sayyiduna Abu Hurayra (Radi Allahu Ta’ala Anhu) reported that the Glorious Prophet of Islam (Peace and Blessings be Upon Him) said: “Five things are from the traditions of the Prophets of the old: circumcision, removing the hair below the navel, trimming the mustaches, cutting the nails, and removing the hair from the armpit”.[Sahih Muslim, Vol. 2, Page 127 Hadith 495]

VII. AlaHadrat Imam Ahmad Rida Khan (Alayhir Rahmah) has quoted a saying of Sayyiduna Ka’ab Ahbar (Radi Allahu Anhu) in his booklet Lum’at al-Duha: “Near to the end of the world, there would be some people who would trim their beards. They are extremely unfortunate. That is, they will have no blessing in religion and in the Hereafter”. [Ihya al-Uloom, Vol. 1, Page 145 | Fatawa Radawiyyah, Vol. 22, Page 651]

VIII. The Beloved and Blessed Prophet (SallAllahu Alayhi wa Sallam) once sent a letter with the message of ‘call to righteousness’ to Sag-e-Iran Khisraw (Parwayz) via Sayyiduna Abdullah Bin Huzafah. Seeing the blessed letter, Khisraw (Parwayz), a cruel and insolent person, turned furious and tore the blessed letter into pieces. Then, Khisraw (Parwayz) issued an order to Bazan, the then governor of Yemen, who had influence over the entire Arab Empire. Bazan called for a troop whose commander’s name was Kharkhasrah. Moreover, another officer named Baniwiyah was also sent along with them to keep an eye on the advances and actions of the Holy Prophet (SallAllahu Alayhi wa Sallam).

When both of these officers were brought into the blessed court of the Beloved Prophet (SallAllahu Alayhi wa Sallam), their neck veins were trembling out of the Prophetic-awe of Beloved Mustafa (SallAllahu Alayhi wa Sallam). Since they were fire-worshippers, they did not have beards, and their mustaches were so big that their lips were covered. They used to call their king Parwayz their ‘lord’. Disturbed upon seeing their beardless faces, the Beloved Prophet (SallAllahu Alayhi wa Sallam) said in disgust, ‘May you be ruined! Who asked you to keep such a face?’ They replied, ‘Our lord ‘Parwayz’ has asked us to do so.’ The Beloved and Blessed Prophet (SallAllahu Alayhi wa Sallam) said,

“But my Rabb (Lord) has ordered me to grow the beard and trim the mustache.”[Madarij al-Nubuwwah, Vol. 2, Pages 224-225 | Fatawa Radawiyyah, Vol. 22, Page 647]

Important Notes:
1. Many of our Muslim brothers have opted to make their beards into a fashion and have a ‘stylish’ effect to them. Many completely shave it off and some leave a bit on the chin. Some keep their beards only 2 fingers long and believe that they’re following the Shari’ah, despite the fact that those who shave all of their beards and those who shave it to less than one fist are all the same in sin in the eyes of Shari’ah. It has been stated in Bahar-e-Shari’at: “To grow the beard is the Sunnah of the prophets. To shave it all or less than a fist is Haraam.” [Bahar-e-Shari'at, Vol. 16, Page 585]

2. Hadrat Shaykh Abd al-Haq Muhaddith-e-Dehlwi (Alayhir Rahmah) has stated: “To shave the beard is Haram, and the way of the English, the Hindus, and monkey dancers. It is wajib to leave the beard to grow to one fist. Those fuqaha (scholars) who have stated that to keep the beard one fist is Sunnat, then this is not because according to them to keep the beard to one fist is not wajib, but in fact “sunnah” in this context means the Islamic way, or because the wujub (necessity) of keeping a beard one fist has been proven from the Sunnah (the ahadeeth – prophetic traditions of the Beloved Prophet), just as the Eid prayers have been called Sunnat, despite the fact that they are wajib.”

3. It has been stated in al-Durr al-Mukhtar (Vol. 2, Page 116), Radd al-Muhtar (Vol. 2, Page 117), al-Bahr al-Ra’iq (Vol. 2, Page 280), Fath al-Qadir (Vol. 2 Page 270), Tahtawi (Page 411) that: [and the words quoted here are of Tahtawi’s] “According to the unanimous opinion, to shave the beard less than a fist as is the way of some westerners and effeminate persons who are fond of make-up like women is not permissible. As regards shaving the whole of the beard, then this is the way of the Jews of India and the fire-worshippers of Iran.” [Hashiyat al-Tahtawi Ala Maraqi al-Falah, Page 411]

4. AlaHadrat, Imam Ahmad Rida Khan (Alayhir Rahmah) have recorded it in Fatawa Radawiyyah, Vol. 22, Page 652: “As long as the beard is shorter than a fist length, it is not Halal to trim it. It is the practice of the eunuch to shorten the beard. And fully shaving it is a tradition of the non-Muslims.” [Ghunyah Zawil Ahkam, Vol. 1, Page 208 | Al Bahr ar-Ra’iq, Vol. 2, Page 490 | Fath al-Qadeer, Vol. 2, Page 270]

5. It is permissible to grow the beard more than the Shari’i limit of one fist. However – according to our Imams and scholars – to let the beard grow such that it becomes extremely out of proportion, and which shall incite people to point fingers and make humor out of that person, is offensive and disapproved of. [Lum’ah al-duha fi I’fa al-Luha (Imam Ahmad Rida Khan), Fatawa Radawiyyah, Vol. 22, Pages 571/573]

6. To shave off completely or trim the beard very short once is a minor sin and to habitually do so is a major sin. This continuous act will make you a Faasiq-e-Mu’lin (certified transgressor) and the Court of Shari’ah will reject you as a valid witness. To perform Salaah with Jama’at behind such a person is forbidden and if Salaah is performed, it will be incumbent to repeat that Salaah. If one does not do so, then one will be a great sinner. [Malfoozat-e-AlaHazrat, Vol. 1, Page 141]

7. It is Haram to shave the beard, either one acts on his own or gets it shaved from someone else and the earning from it is also Haram. [Waqar-ul-Fatawa, Vol. 1, Page 259]
