A video of the powerful address, in which he spoke of the need to come together and criticised those who have previously "demonised particular groups", has gone viral.
A day after the horrific terrorist attack that shook us all, the world is still making sense of the tragedy.
"I'm gutted and I'm scared, and I feel overcome with utter hopelessness", Aly said.
Likening yesterday's events to similar attacks on places of worship in Quebec City, London, Pittsburgh, and Charleston in recent years, Aly said he had attended a service at his own mosque the morning of the shooting. "I'm simply not. There's nothing about what happened in Christchurch today that shocks me".
Aly offers "I know how quiet, how still, how introspective those people would have been before they were suddenly gunned down, how separated from the world they were feeling until the world came in and tore their lives apart", before adding "And I know that the people who did this knew well enough how profoundly defenseless their victims were in that moment".
Aly called the Christchurch shooting "slaughter by appointment", since the shooters chose the precise timing of prayers to carry out their attack.
Aly also took aim at other controversial comments made about Muslim migrants to Australia by other Australian political parties in the past, including one allegedly made by Morrison himself eight years ago.
"It feels like fish in a barrel", he said. He then appeared to read excerpts from it, attacking Islam as a religion of violence and saying that those who are Muslim should expect violence against them.
"How do those words sound when I tell you they weren't part of the manifesto? They were published (on Friday), after the attacks, on an Australian parliament letterhead", he said.
Senator Anning has refused to apologise and even doubled down on the sentiments, which essentially blamed Muslim people for the attacks. "I have something to ask", Aly continued.
"Don't change your tune now because the terrorism seems to be coming from a white supremacist". Now we understand that this is not a game. Terrorism doesn't choose its victims selectively. We are one community.
