(64) باب تَقْلِيمِ الأَظْفَارِ
Narrated Nafi`:
Ibn `Umar said, The Prophet (ﷺ) said, 'Do the opposite of what the pagans do. Keep the beards and cut the moustaches short.' Whenever Ibn `Umar performed the Hajj or `Umra, he used to hold his beard with his hand and cut whatever remained outside his hold.
