Abdullah ibn Amr reported:

Abdullah ibn Amr reported: The Prophet, peace and blessings be upon him, mention prayer one day and he said, “Whoever guards his prayers will have light and clarity and salvation on the Day of Resurrection. Whoever does not guard his prayers will not have light nor clarity nor salvation, and on the Day of Resurrection he will be with Qarun and Pharaoh and Haman and Ubay ibn Khalaf.”
