Q: Can I make a vow to fast for 1 week for the pleasure of Allah and in return ask Allah for the recovery of my mother in-law who is currently very sick? She will be going for liver biopsy on Monday morning and I want to fast so that Allah can make it easy for her and make her results negative. An urgent reply will be highly appreciated.
A: It is permissible.
And Allah Ta’ala (الله تعالى) knows best.
