Sahih Muslim, 1715

Abdullah b. 'Amr reported:It was narrated to me that the Messenger of Allah (ﷺ) had said: The prayer observed by a person sitting is half of the prayer. I came to him (ﷺ) and found him praying in a sitting position. I placed my hand on his head. He said: O 'Abdullah b. 'Amr, what is the matter with you? I said: Messenger of Allah, it has been narrated to me that you said: The prayer of a man in a sitting position is half of the prayer, whereas you are observing prayer sitting. He (the Holy Prophet) said: Yes, it is so, but I am not like anyone amongst you

Rapporté par Abdullah b. ‘Amr : On m’a rapporté que le Messager d’Allah ﷺ avait dit : « La prière accomplie assis compte pour la moitié de la prière. » Je suis allé le voir ﷺ et je l’ai trouvé en train de prier assis. J’ai posé ma main sur sa tête. Il a dit : « Ô Abdullah b. ‘Amr, qu’as-tu ? » J’ai dit : « Messager d’Allah, on m’a rapporté que tu as dit : “La prière d’un homme assis compte pour la moitié de la prière”, alors que tu pries assis. » Il a répondu : « Oui, c’est vrai, mais je ne suis pas comme n’importe lequel d’entre vous. »
