صحيح مسلم 1308

Abdullah b. Zubair narrated on the authority of his father that when the Messenger of Allah (ﷺ) sat for supplication, i. e. tashahhud (blessing and supplication), he placed his right hand on his right thigh and his left hand on his left thigh, and pointed with his forefinger, and placed his thumb on his (milddle) finger, and covered his knee with the palm of his left hand

Rapporté par Abdullah b. Zubair d’après son père رضي الله عنه : Lorsque le Messager d’Allah ﷺ s’asseyait pour l’invocation, c’est-à-dire le tashahhud, il posait sa main droite sur la cuisse droite, sa main gauche sur la cuisse gauche, il pointait l’index, posait le pouce sur le majeur, et couvrait son genou de la paume de la main gauche
