“Avoid the seven destroyers.”
They said: “O Allah’s Messenger! And what are they?”
PHe replied: “Committing Shirk with Allah, magic, to kill someone that Allah has prohibited – except for just cause – consuming Riba (Usury), consuming the wealth or property of an orphan, to flee on the day of the march (to battle), and to slander the chaste, unaware, believing women.”
(Bukhari)
