The reciter: And Zuhayr ibn Harb narrated to me, saying: Jarir narrated to us from Mansur from Hisham ibn Yusuf from Abu Yahya from Abdullah ibn Amr, who said:
I was told that God’s Messenger had said, “Prayer engaged in by a man while sitting counts as half the prayer,” so I went to him and I found him praying while sitting, and I put my hand on his head. He said, “What is the matter with you, ‘Abdallah b. ‘Amr? ’’ I replied, “I have been told, Messenger of God, that you said that prayer engaged in by a man while sitting counts as half the prayer, yet you yourself are praying while sitting.” He said, “Yes, but I am not like one of you.”
حُدثت أن رسول الله صلى الله عليه وسلّم قال: صلاة الرجل قاعدا نصف الصلاة، قال: فأتيته فوجدته يصلي جالسا فوضعت يدي على رأسه فقال: مالك يا عبد الله بن عمرو؟ قلت: حُدثت يا رسول الله أنك قلت: صلاة الرجل قاعدا على نصف الصلاة، وأنت تصلي قاعدا قال: أجل ولكني لست كأحد منكم Mishkat al-Masabih 1252.
