Intertwine the beard
Sayyidina Hassan Ibn Bilal (RA) said that he saw ammar ibn yasir (RA) perform ablution,
He ran his fingers through beard so Hassan (RA) asked him, "Do you interwine your
beard?" Ammar (RA) said , "Why should I not do it when I did see Allah’s Messenger
(SAW) run fingers through his beard"
[Ibn e Majah 429,430]
