Sayyiduna Anas (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "Seventy thousand of my Ummah will enter Paradise." The people said: "O Messenger of Allah! Increase it for us." The Prophet (peace and blessings be upon him) said: "With every single person there will be seventy thousand people." The people said: "O Messenger of Allah! Increase it for us." He was on a sand dune, and he scooped up (sand) with both his hands. The people said: "O Messenger of Allah! Increase it for us." The Prophet (peace and blessings be upon him) said: "It will be this," and he scooped up (sand) with both his hands. The people said: "O Prophet of Allah! May Allah Almighty distance the one who enters Hell even after this."
Abu Ya'la recorded it.
