Buraida (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu ‘alayhi wa sallam) said,
“He who misses the `Asr Salat (deliberately), his deeds will be rendered null and void.”
[Al-Bukhari] [RiyadusSaliheen, Darussalam Translation].
The Prophet [sallal-laahu-alayhi-wasallam] said,
“Whoever misses the Asr prayer [i.e. intentionally] until its time elapses, it is as if he has lost his family and his wealth’’
[Saheeh Al-Bukhaari, Hadeeth Number 552. Vol 1 Darussalam Publications]
