Riyad as-Salihin #935

The Prophet (ﷺ) said, "Keep away from the seven fatalities." It was asked: "What are they, O Messenger of Allah?" He (ﷺ) replied, "Associating anything with Allah in worship (i.e., committing an act of Shirk), sorcery, killing of one whom Allah has declared inviolable without a just cause, devouring the property of an orphan, the eating of usury (Riba), fleeing from the battlefield and accusing chaste believing women, who never even think of anything touching their chastity.".
