Ash-Shaykh Bin Baaz, may Allaah have mercy upon him, said:
“…Some of them [of the people] hold on to what was narrated from Ibn Umar, may Allaah be pleased with him, during Hajj and Umrah that he used to trim his beard, according to what he understood from the statement of Allaah:
(…ثُمَّ لْيَقْضُوا تَفَثَهُمْ)
‘Then let them complete the rites prescribed for them…’
He used to see Qadaa at-tafath (completing the rites) was trimming the beard. This [understanding] is also incorrect because it is not permissible for a Muslim if he comes to know of a Sunnah of the Prophet, alaihi as-salaatu was salaam and that which he, alaihi as-salaatu was salaam, was upon to oppose it for anyone else’s opinion. So Ibn Umar, may Allaah be pleased with him, was mistaken in this [action]; he does not have with him a proof from the Sunnah indicating [the permissibility] of that. So it is not permissible to follow him while being in opposition to the Sunnah, but at the same time Ibn Umar, may Allaah be pleased with him, used to trim his beard in Hajj and Umrah only. As for them [those claiming to follow Ibn Umar] they shave it or trim it wherever and whenever not only in Hajj and Umrah, so, they are in opposition to the Hadeeth [that which is indicating that the beard should be left] and also they are in opposition to Ibn Umar.
