It is too late! The vow had been already made and you must fulfill it if what you asked for happens.

I made a vow to fast two months when my father is fully recovered from his massive heart attack. However, since then I read in a Sahih Hadith that Rasulullah SAW discouraged this type of vow because it does not change Qadr I want to know if it is permissible to change my vow to me fasting two months regardless of whatever happens?

I recently joined a islamic organisation who are involved in various social projects for the downtroden muslims in India. However, when joining, a person held my hand to recite after him. It goes like “I pledge myself to the organisation and this bayyah is between me and Allah and I will give every second of my life dedicated to this organisation etc” is this valid?can I leave the org if i wish?
