Ali bin Abu Talib reported,
I was with the Prophet ﷺ when Abu Bakr and Umar 
approached. He said, "Ali, these two are the masters of the elders and youth of the people of Paradise, after the prophets and messengers."
Ahmad 602
Sahihحدثنا عبد الله حدثني وهب بن بقية الواسطي حدثنا عمر بن يونس يعني اليمامي عن عبد الله بن عمر اليمامي عن الحسن بن زيد بن حسن حدثني أبي عن أبيه
عن علي رضي الله عنه قال
كنت عند النبي ﷺ فأقبل أبو بكر وعمر رضي الله عنهما فقال يا علي هذان سيدا كهول أهل الجنة وشبابها بعد النبيين والمرسلين
Its isnad is sahih. Umar bin Yunus Yamami is thiqah, thabit. In H it appears as Amr bin Yunus, which is an error. Abdullah bin Umar Yamami is also called Abdullah bin Muhammad, and is known as Ibn Rumi. Ibn Hibban and others declared him thiqah, and Muslim narrated from him, naming him Abdullah bin Muhammad. See Tahdheeb 6:21-22 and Tajeel 230.Hasan bin Zayd bin Hasan bin Ali bin Abu Talib is thiqah. Malik and others narrated from him, and whoever declared him daif was mistaken. He is the father of Sayyidah Nafisah. His father, Zayd bin Hasan, is thiqah, and died around the year 120, at the age of 90.This hadith was also narrated by Tirmidhi, 4:310, and Ibn Majah, 1:25-26, with two other daif isnads. This hadith and the one before it are among the additions of Abdullah bin Ahmad.
