Q- I am aware of the Hadith regarding Salah not being accepted for forty days for the one who drinks an alcoholic beverage. What is the authenticity of the following Hadith which states a similar punishment for one who consumes haram food? من أكل لقمة من حرام لم تقبل منه صلاة أربعين ليلة
Whoever consumes a haram morsel, his Salah will not be accepted for forty (40) days
Imam Daylami (rahimahullah) has recorded this narration. However, ‘Allamah ‘Iraqi and Hafiz Ibn Hajar (rahimahullah) have declared the text unreliable (munkar). (Al Mughni ‘An Hamlil Asfar, Hadith: 1655, Lisanul Mizan, vol. 6 pg. 345. Also see: Tanzihush Shari’ah, vol. 2 pg. 267)
The Hadith is therefore not suitable to quote. However, the subject matter is supported by a Hadith in Sahih Muslim which states that consuming haram is a reason for du’a [which is an ‘ibadah] not being accepted.
And Allah Ta’ala Knows best
