"Our hearts are literally hurting. But We are so happy daddy is free now. We all tried to stay strong and whispered in his ear, 'You can go now. We will be okay. We love [you]. Thank you. You can go back to God now.' All of us were around him hugging and kissing him and holding hands, chanting the Islamic prayer. All of his organs failed but his heart wouldn't stop beating. For 30 minutes his heart just keep beating. No one had ever seen anything like it. A true testament to the strength of his Spirit and Will! Thank you for all your love and support!!!"
