What is your opinion on reading Qur’aan over olive oil? Is it possible for more than one person to read into one bottle?
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.
