Musnad Ahmad 30:1493

Hassan narrated to us, Ibn Lahi'ah narrated to us, Abu Yunus narrated to us, from Abu Hurairah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Seventy thousand from my Ummah will enter Paradise without reckoning." Ukashah ibn Mihsan said: "Supplicate to Allah for me, O Messenger of Allah, that He makes me one of them." The Messenger of Allah (peace and blessings of Allah be upon him) said: "O Allah, make him one of them." Then another man said: "O Messenger of Allah, supplicate to Allah that He makes me one of them." He said: "Ukashah has preceded you to it."
