Abu Hurairah narrated that the Messenger of Allah (s.a.w) said:
"Do you crowd one another in order to see the moon on the night of a full moon? Do you crowd one another in order to see the sun?" They said: "No." He said: "So verily, you shall see your Lord as you see the moon on the night of a full moon, you shall not crowd one another to see Him." (ID)
