Occupy yourselves with that which your Lord has called you to do. Do not be concerned with those who harm you, whether they be from amongst you or from outside. If you do not seek to stand up for yourselves then God all-Mighty will do so for you and subsequently take over your affair, and if you stand up for yourselves then He will leave the affair in your hands and you will be left helpless, and God has power over everything.
(Sidi Qasim al-Khassasi:) ‘Don't ever be concerned with those who come to harm you. Instead, occupy yourself with God, and He will turn them away. He is the one who brought them to you in order to test whether you were being truthful in your claim. How many a man has slipped up on this point, and become concerned with defending himself against those who harmed him, therefore causing the harm to persist and falling into sin at the same time. If only he turned to his Lord He would turn them away from him, and suffice him.’ Peace.
