should it lengthen the beard?

Assalamualaikum...!!! Hello Reader, thank you for taking the time to read. may Allah give grace and guidance.
today I will discuss about the law of keeping the beard

there is a saheeh hadeeth from the Prophet sallallaahu 'alaihi wa sallam issued by Imam Al-Bukhari and Muslim in the book of the Sahih both of the hadith of Ibn Umar Radhiyallahu' anhuma he said. Rasulullah sallallaahu 'alaihi wa sallam said.

العربية

"Meaning: Differentiate the idolaters, cut the mustache (to the finish) and perfect the beard (let it grow thick, -peny) '[1]

In the Muslim shahih from Abu Hurairah Radhiyallahu 'anhu, he said, Rasulullah sallallaahu' alaihi wa sallam said. "(Meaning): Cut a mustache and leave the beard long, separate the Magi" [2]

Imam An-Nasai in his sunan issued a hadith with a saheeh sanad from Zayd ibn Arqam Radhiyallahu 'anhu, he said, Rasulullah sallallaahu' alaihi wa sallam said.

من لم يأ خذ من يأخذ من شاربه فليس منا

"It means: Whoever has never taken from his mustache (cut it), then he is not of our class" [3]

The great Al-Allamah and the famous Al-Hafiz, Abu Muhammad bin Hazm said, "The scholars have agreed that cutting off the mustache and allowing the beard to grow is fardlu (obligatory)"

The hadiths about this and the clerics' sayings about cutting out the mustache and multiplying the beard, glorifying and allowing it to be extensively numerous, it is difficult to calculate the quantity in this short treatise.

From the hadiths in advance and the excerpt of ijma by Ibn Hazm the answers to these three questions are summarized; that maintaining, multiplying and allowing the beard to lengthen is fardhu, should not be abandoned because the Messenger of Allah commanded thus while his command contains mandatory meaning as the word of Allah Ta'ala.

وما نهاكم عنه فانتهوا

"Meaning: And what is forbidden to you then leave" [Al-Hasyr: 7]

Likewise, cutting the mustache of the legal obligation but cutting out is more afdhal (main), while reproducing or leaving it for granted, then it should not be law because it contradicts the word of the Prophet sallallaahu 'alaihi wa sallam: قصوا الشوارب "Potonglsh whiskers" أحفوا الشوارب "Cut a mustache out", جزوا الشوارب "Cut a mustache", من لم يأخذ من شاربه فليس منا "Whoever does not take from his mustache (cut it) then he is not of our class"

The four lafazh hadith, all of which are contained in the narrations of hadith from the Prophet sallallaahu 'alaihi wa sallam, while in the last lafazh there is a serious threat and a very firm warning. This then contains the obligatory consequences of a Muslim being careful of the prohibition of Allah and His Apostle and hastening to obey the commands of Allah and His Messenger.

It is also known that reproducing a mustache and allowing it is an act of sin and immorality. Likewise, to shave his beard and cut him off, including sinfulness and sinfulness that can reduce faith and weaken it and worry about the wrath of Allah and His punishment.

In the above mentioned hadiths there is an indication that lengthening the mustache and shaving the beard and cutting it down includes deeds resembling the magi and the polytheists when it is well known that resembling them is an evil deed, it should not be done according to the word of the Prophet 'Alaihi wa sallam.

من تشبه بقوم فهو منهم

"Meaning: Whoever resembles a people, he belongs to them" [4]

I hope this answer is sufficient and satisfying.

Wallahu waliyyut taufiq Washallahu wa sallam 'ala Nabiyyina Muhamad wa waii wa shahbih.
