Musnad Ahmad 962:96

Al-Hudhayl ibn Maymun al-Kufi al-Ju'fi narrated to us—he used to sit in the mosque of the city, meaning the city of Abu Ja'far; Abdullah said: This is an old Kufi sheikh—from Matrah ibn Yazid, from Ubaydullah ibn Zahr, from Ali ibn Yazid, from al-Qasim, from Abu Umamah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I entered Paradise and heard a rustling sound in front of me. I said: 'What is this?' It was said: 'Bilal.' I proceeded, and behold, the majority of the people of Paradise were the poor among the Emigrants (Muhajirun) and the offspring of the Muslims. I did not see anyone in it fewer than the wealthy and the women. It was said to me: 'As for the wealthy, they are here at the gate, being held to account and examined. As for the women, the two red things have distracted them: gold and silk.'" He said: "Then we went out from one of the eight gates of Paradise. When I was at the gate, a scale was brought and I was placed in one pan, and my nation was placed in the other pan, and I outweighed them. Then Abu Bakr was brought and placed in a pan, and all of my nation was brought and placed in a pan, and Abu Bakr outweighed them. Then Umar was brought and placed in a pan, and all of my nation was brought and placed, and Umar outweighed them. Then my nation was presented to me, man by man, and they began to pass by. I found the delay of Abd al-Rahman ibn Awf to be long, then he came after I had despaired. I said: 'Abd al-Rahman?' He said: 'May my father and mother be sacrificed for you, O Messenger of Allah! By the One who sent you with the truth, I did not reach you until I thought that I would never see you except after great trials.' I said: 'And why is that?' He said: 'Because of the abundance of my wealth, I am being held to account and examined.'"
