Abdullah bin Abbas reported,

I was standing among a group of people who were praying to Allah for Umar bin Khattab, whose body had been placed on his bier, when suddenly a man behind me rested his elbow on my shoulder and said, "May Allah have mercy on you. I always hoped that Allah would place you with your two companions, because I often heard the Messenger of Allah ﷺ say, 'I went with Abu Bakr and Umar,' 'I did such and such with Abu Bakr and Umar,' and 'I set out with Abu Bakr and Umar.' So I truly hoped that Allah would place you alongside them."I turned around, and there was Ali bin Abu Talib.

عن ابن عباس رضي الله عنهما قال

إني لواقف في قوم فدعوا الله لعمر بن الخطاب وقد وضع على سريره إذا رجل من خلفي قد وضع مرفقه على منكبي يقول رحمك الله إن كنت لأرجو أن يجعلك الله مع صاحبيك لأني كثيرا ما كنت أسمع رسول الله ﷺ يقول كنت وأبو بكر وعمر وفعلت وأبو بكر وعمر وانطلقت وأبو بكر وعمر فإن كنت لأرجو أن يجعلك الله معهما فالتفت فإذا هو علي بن أبي طالب
