 According to Ali, "Sakinah is a sweet breeze/wind, whose face is like the face of a human".Mujahid mentions that "when Sakinah glanced at an enemy, they were defeated", and ibn Atiyyah mentions about the Ark of the Covenant ("at-Tabut"), to which the sakina was associated, that souls found therein peace, warmth, companionship and strength.According to Sunni Islam, when Muhammad was persecuted in Mecca, the time came for him to emigrate to Medina.
