Ibn Ad-Dailami rode looking for 'Abdullah bin 'Amr bin Al-'As. Ibn Ad-Dailami said: "I entered upon him and said: 'O 'Abdullah bin 'Amr, did you hear the Messenger of Allah say: If a man among my Ummah drinks Khamr, Allah will not accept his Salah for forty days.'"
Sunan an-Nasa'i Book 51, Hadith 126
← Previous Hadith That his father used to say: "I do not see any difference between drinking Khamr and worshipping this column instead of Allah the Mighty and Sublime."

Sunan an-Nasa'i Book 51, Hadith 125 Next Hadith → "If a judge accepts a gift he has consumed something unlawful, and if he accepts a bribe, that takes him to the level of Kufr." Masruq said: "Whoever drinks Khamr, he has committed (an act of) Kufr, and his Kufr is that his Salah does not count."

Sunan an-Nasa'i Book 51, Hadith 127
