But if, among your companions, you come across someone who is careless of your rights, who does not care whether you perish or survive—indeed, who may even be working for your destruction—then beware of him, for he is lethal poison; we seek Allah’s protection. Do not go near such people; instead, keep your distance. Flee from them as you would flee from a lion.

The truly fortunate person is not dull like a stone; he is sharp like glass—solid, yet transparent, allowing one to see clearly what lies beyond. Thus, he combines strength and firmness with wakefulness, so that he can discern—almost as though gazing into the unseen—what benefits him from what harms him. He therefore pursues what will help him and avoids what will harm him. We ask Allah to grant success to us and to all Muslims.
