A man reported,

I set out from my family heading to the Prophet ﷺ, and there I found him standing with a man who was facing him in conversation. I thought the two of them had some matter to attend to.The Ansari said, "By Allah, the Messenger of Allah ﷺ stood for so long that I began to feel sorry for the Messenger of Allah ﷺ because of how long he was standing. When he finished, I said, 'Messenger of Allah, that man stood with you so long that I began to feel sorry for you because of the length of his standing.'"The Prophet ﷺ asked, "Did you see him?"I replied, "Yes."He asked, "Do you know who he was?"I said, "No."He said, "That was Jibreel . He kept urging me concerning the neighbor until I thought he would make him an heir. Indeed, had you greeted him with peace, he would have returned the greeting to you."

عن رجل من الأنصار قال

خرجت من أهلي أريد النبي ﷺ فإذا أنا به قائم، ورجل معه مقبل عليه، فظننت أن لهما حاجة، قال: فقال الأنصاري: والله لقد قام رسول الله ﷺ حتى جعلت أرثي لرسول الله ﷺ من طول القيام، فلما انصرف، قلت: يا رسول الله لقد قام بك الرجل حتى جعلت أرثي لك من طول القيام قال: ولقد رأيته، قلت: نعم قال: أتدري من هو؟ قلت: لا، قال: ذاك جبريل عليه السلام مازال يوصيني بالجار حتى ظننت أنه سيورثه، ثم قال: أما إنك لو سلمت عليه رد عليك السلام.
