Abdullah on Jihad: Start with the jihad against the soul

Hannan ibn Kharija reported: I said to Abdullah ibn ‘Amr, may Allah be pleased with him, “What do you say about jihad and military campaigns?” Abdullah said, “Begin with your soul and wage jihad against it. Begin with your soul and wage a military campaign against it.”
