´It was narrated that Ibn 'Umar said:` "Whoever drinks Khamr and does not get intoxicated, his Salah will not be accepted so long as any trace of it remains in his belly or his veins, and if he dies he will die a Kafir. If he becomes intoxicated his Salah will not be accepted for 40 nights, and if he dies during them, he will die a Kafir." (Sahih Mawquf)
Explanation & Benefits
Hafiz Muhammad Ameen
(1) Imam Nasa’i rahimahullah’s intent is that when Fudayl bin ‘Amr narrated this narration, he said: “from Mujahid, from Ibn ‘Umar,” i.e., he considered it as being from the Musnad of ‘Abdullah bin ‘Umar radi Allahu anhu. Whereas when Yazid bin Abu Ziyad narrated this from Mujahid, he said: “from Ibn ‘Umar,” i.e., he narrated it as being from the Musnad of ‘Abdullah bin ‘Umar radi Allahu anhu. And Allah knows best.
(2) The death of a disbeliever: because his prayer is not accepted, he becomes like a disbeliever, and this is an extremely repugnant state. May Allah protect us from it.
