Urgent Dua Needed for a Beloved Uncle

As-salamu alaykum, dear brothers and sisters. I come to you with a heavy heart, urgently seeking your sincere prayers. My uncle underwent heart surgery yesterday. After he woke from the procedure, he suffered a cardiac arrest and is now on life support. The doctors have said that if there is no improvement, they may have to remove the support tomorrow. We are clinging to hope and praying for a miracle from Allah. Please, in your kindness, make dua for his complete recovery and for ease for our family during this trial. Jazakum Allahu khayran.
