Musnad Ahmad 32:1064

Bahz narrated to us, Abu Hilal narrated to us, he said: Qatadah narrated to us, from Anas, that the Prophet, peace and blessings of Allah be upon him, said: "My Lord promised me that He would enter one hundred thousand of my nation into Paradise." Abu Bakr said: "O Messenger of Allah, increase us." He said to him: "And like this," and he gestured with his hand. He said: "O Prophet of Allah, increase us." He said: "And like this," and he gestured with his hand. He said: "O Prophet of Allah, increase us." He said: "And like this." Umar said to him: "That is enough for you, O Abu Bakr." He said: "What is between us and you, O son of Al-Khattab?" Umar said to him: "Indeed, Allah is capable of entering all people into Paradise with a single handful." The Prophet, peace and blessings of Allah be upon him, said: "Umar has spoken the truth."
