Ubaidullah bin Mqsm عبيد الله بن مقسم · The Book of the Prayer

The Messenger of Allah said: "The one who misses the 'Asr prayer, it is as if he has been cheated out of his family and wealth."

"The idolaters kept the Prophet from the 'Asr prayer until the sun had set. He said: 'They kept us from performing the middle prayer; may Allah fill their graves and their houses with fire.'"
