1. Is it Obligatory to believe in Taqdeer (Destiny)? 2. Can Dua change Taqdeer? I have heard that Taqdeer does not change but i have also heard that dua can change taqdeer. Please clarify.
Believing in pre-destiny and in Allah’s preordination is a pillar of
faith that a person is not a Muslim without it.
There are two type of decree; changeable and unchangeable.
The unchangeable one, only Allah knows about.
The changeable one is the one we can change through Dua’a and other deeds.
