Praise be to Allaah.
There is no reason why aayaat and du’aas cannot be
recited over water, such as Zamzam water, or olive oil, then it may be wiped onto the sick
person. And there is no reason why more than one person should not recite into that
bottle.
From Al-Lu’lu’ al-Makeen min Fataawaa Ibn Jibreen.
