It is narrated from Sayyiduna Abdullah bin Amr bin Aas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) mentioned prayer one day and said: Whoever guards the prayer properly, it will be for him a light, a proof, and salvation on the Day of Resurrection. And whoever does not guard it properly, then on the Day of Resurrection it will be neither a light for him, nor a proof, nor salvation, and such a person will be with Qarun, Pharaoh, Haman, and Ubayy bin Khalaf.
