سنن أبي داود

Abu Hurairah said : The people asked : Messenger of Allah! Shall we see our lord, the Exalted, on the Day of resurrection? He replied : Do you feel any trouble in seeing the sun at noon when it is not in the cloud? They said: No. He asked : Do you feel any trouble in seeing the moon on the night when it is full and not in the cloud? They replied: No. He said: By him in whose hand my soul is, you will not feel any trouble in seeing him except as much as you feel in seeing any of them.
