The Messenger of Allah (swt) (peace be upon him and his family) said: "The first matter that Allah (swt), the Almighty and Majestic, will judge on the Day of Judgment is bloodshed. The sons of Adam (as) will be brought forward, and judgment will be passed between them. Then those who followed them among the people of bloodshed will be judged until none of them remain. After that, the murdered will bring forth his killer, and his blood will gush onto the killer's face. The murdered will say: 'You killed me,' and the killer will not be able to conceal any word from Allah (swt)."
