An Australian man played the Muslim call to prayer adhan in his house to show solidarity with Muslims after 49 people were killed when terrorist Brenton Tarrant opened fire on worshippers attending Friday prayers at two mosques in Christchurch on Friday.

"I live in country Australia and stand with #Muslims around the world. As I thought about #ChristchurchAttack I wanted to play the call to prayer at home at sunset. I'm not religious so hope that is not disrespectful. It is my gesture of solidarity," he wrote on his Twitter account.

The gesture was widely welcomed by social media users as @lachdrummond received thousands of retweets and replies to his post.

"I'm overwhelmed by the shared love and positivity out there, despite the darkness," he wrote.
