Q: What is the ruling on shaving the hair of the cheeks and letting that of the chin grow?
Trim closely the mustache, and let the beard grow to be contradictory to the unbelievers. (Agreed upon by AlBukhari and Muslim)
Trim closely the mustache, and let the beard grow to be contradictory to the unbelievers. (Related by AlBukhari in the Sahih)
Ordered us to trim mustaches and let the beards grow. (Agreed upon by Imams AlBukhari and Muslim)
Trim closely the mustache, and grow beard, and thus act against the Magi.
The believers should let the beard grow and cut the mustache as our Prophet Muhammad (peace be upon him) ordered us. This involves great goodness besides reviving the Sunnah (whatever is reported from the Prophet) and abiding by his orders. This also entails avoiding resemblance to the unbelievers and women. The Mu'min (believer) should not be deceived by the multitude of men who shave their beards and should not imitate them for they contradict the purified Shar` (Law) and the order of the Messenger (peace be upon him) whom Allah sent as a guide, a bearer of glad tidings, and a warner.
And whatsoever the Messenger (Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) gives you, take it; and whatsoever he forbids you, abstain (from it).
And let those who oppose the Messenger's (Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) commandment (i.e. his Sunnah legal ways, orders, acts of worship, statements) (among the sects) beware, lest some Fitnah (disbelief, trials, afflictions, earthquakes, killing, overpowered by a tyrant) should befall them or a painful torment be inflicted on them.
and whosoever obeys Allâh and His Messenger (Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) will be admitted to Gardens under which rivers flow (in Paradise), to abide therein, and that will be the great success. And whosoever disobeys Allâh and His Messenger (Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ), and transgresses His limits, He will cast him into the Fire, to abide therein; and he shall have a disgraceful torment.
There are many other Ayahs (Qur'anic verses) that urge people to obey Allah (Glorified be He) and His Messenger (peace be upon him) and warn against disobeying Allah and His Messenger. Allah is the Grantor of success.
