Does cutting off the Dhuhr prayer to answer an emergency call and then completing it after the conversation invalidate the prayer?

It is permissible to interrupt the prayer to answer the phone if not answering would lead to a Sharia-prohibited harm or an unbearable penalty, bearing in mind that intentional speech during prayer invalidates it. Al-Mazari stipulated that intentional speech to rescue a Muslim invalidates the prayer, even if it is obligatory. Similarly, intentional speech during prayer for reasons other than correcting it invalidates it by consensus. As for unintentional speech, it does not invalidate the prayer according to the majority of scholars, while others hold that it does. Based on this, the speech you uttered invalidates the prayer and necessitates its immediate repetition.
