Waki' bin Hudus narrated that his paternal uncle Abu Razin said:
"I said: 'O Messenger of Allah, will we see Allah on the Day of Resurrection? And what is the sign of that in His creation?' He said: 'O Abu Razin, do each of you not see the moon individually?' I said: 'Of course.' He said: 'Allah is Greater, and that is His sign in His creation.'"
