Questioner:
May Allāh be benevolent to you. The questioner says: What are the means to strengthening al-Eemān (faith).
Shaykh Zayd bn Muḥammad al-Madkhalī:
Performing acts of obedience and abandoning acts of disobedience. That is what strengthens the faith. Performing acts of obedience and persistence upon it and hastening towards it and abandoning acts of disobedience; from speech and actions, apparent and hidden. These strengthen the faith.
