Every once in a while, you'll see an ambulance drive by, sirens wailing and everything. You stop, and wonder to yourself if everything will be okay. (especially if the ambulance belongs to Hatzalah)
This is probably a good time to offer up a prayer for the well-being of the unknown patient. You could probably say something in English, but Hebrew is better. You wouldn't be wrong for saying "אחינו כל בית ישראל," which is the general prayer for people in distress, but it feels a little too vague.
Has anyone composed a prayer for one who sees an ambulance driving past?
