Musnad Ahmad 30:1937

'Affan narrated to us, Wuhayb narrated to us, Mus'ab ibn Muhammad ibn Shurahbil narrated to us, from Abu Salih al-Samman, from Abu Hurayrah, who said: They said, "O Messenger of Allah, will we see our Lord, the Mighty and Majestic, on the Day of Resurrection?" He said, "Do you see the sun at midday when there is no cloud in the sky?" They said, "Yes." He said, "Do you see the moon on the night of the full moon when there is no cloud in the sky?" They said, "Yes." He said, "By the One in Whose hand is my soul, you will surely see Allah, the Mighty and Majestic, and you will not be harmed in seeing Him, just as you are not harmed in seeing them."
