The mildest punishment (for drinking) is eighty (stripes) and 'Umar their prescribed this punishment.
The Book of Legal Punishments - Sahih Muslim 1706a
In the name of Allah, the Most Gracious, the Most Merciful. This narration from the Sahih Muslim collection addresses the legal punishment for consuming intoxicants, which the rightly-guided Caliph 'Umar ibn al-Khattab (may Allah be pleased with him) established as eighty lashes.
The scholars of Islam have explained that this punishment represents the minimum prescribed for drinking alcohol, as intoxicants are considered among the major sins that corrupt both the individual and society. The wisdom behind this punishment is to serve as a deterrent while allowing for judicial discretion in cases where circumstances may warrant a more severe penalty.
Imam al-Nawawi, in his commentary on Sahih Muslim, clarifies that the eighty lashes became the standard punishment during 'Umar's caliphate after consultation with the Companions, establishing it as the legal precedent (hadd) for this offense in Islamic jurisprudence.
