Musnad Abu Ya'la al-Mawsili 129:66

Muhammad ibn Abi Bakr al-Muqaddami narrated to us, Abd al-Qahir ibn al-Sari narrated to us, Humayd narrated to us, from Anas, from the Prophet, may Allah bless him and grant him peace, who said: "Seventy thousand from my nation will enter Paradise." They said, "Increase us, O Messenger of Allah." He said, "For every man, seventy thousand." They said, "Increase us, O Messenger of Allah." He was upon a sand dune, so he scooped with his hand. They said, "Increase us, O Messenger of Allah." He said, "This," and he scooped with his hand. They said, "O Prophet of Allah, may Allah distance those who enter the Fire after this."
