Andi Syamsul Bahri, the imam of the Al-Ula Mosque in the city of Balikpapan in the East Kalimantan region of Indonesia, died of a heart attack during the morning prayer on January 2. The congregation did not notice the incident for a while because they were prostrating, which made them unable to see him. His condition was noticed shortly after and someone among the crowd stepped forward to resume the prayers.
