If they believe as you believe, they are guided. Allah suffices.
Their choice, your peace
The verse follows the creed of all prophets. If they believe in what you believe, they are guided. If they turn away after the proof is shown, they are only in opposition. Ibn Kathir: Allah will aid the believers and suffice them.
You have explained your faith to your colleague, your neighbour, your brother in law. Some get it. Some argue, some mock. You do not have to carry their response. Allah is enough for you.
If people reject my faith, I am exposed and alone.
Allah suffices me. Their acceptance is guidance for them; their rejection does not undo me.
When someone dismisses your faith today, say quietly: hasbiyallah, Allah is enough for me.
