On Praying Over a Muslim who Committed Suicide

Answered by Sayyidi al-Ḥabīb `Umar bin Hafīẓ (may Allāh preserve him and benefit us by him).

If a Muslim commits suicide should we pray for them as we would pray for any Muslim that has died?

It is permissible to pray for any Muslim, unless we are certain that they have left Islam or fallen into disbelief before dying.
