Undertaking an oath in anger: is kaffara required? ~{Details- http://aydnajimudeen.blogspot.com/}

Question:
If you could just provide me with a ''yes'' or ''no'' answer that
would suffice insha'Allah. My friend made an oath andbroke it, but it
was in a fit of anger. Let me tell you what was said:
Answer:
In the Name of Allah, Most Merciful and Compassionate
Yes the kaffara is required as he did not fulfil it, even though he
was in a fit of anger.
And Allah knows best
