Those who refuse His signs are left without guidance.
Guidance needs a heart that wants it
Ibn Kathir says Allah does not guide those who turn away from remembering Him, who are heedless, and who have no intention of believing. Such people will not be guided by the signs, because they never wanted to be.
You say you want to change, but you avoid every talk, every reminder, every friend who might push you. Guidance comes to those who want it. Wanting it starts with not running from it.
If Allah wanted me guided, it would just happen.
Guidance meets those who turn toward it; refusing it closes the door.
Make a sincere dua today: O Allah, make me want what You want for me.
