Ibn Mas'ud (May Allah be pleased with him) reported: The Prophet (ﷺ) said,
"The first matter concerning which people will be judged on the Day of Resurrection will be matter of bloodshed." Sahih al-Bukhari, Muslim
And you are not [engaged] in any matter or recite any of the Qur'an and you [people] do not do any deed,
except that We are witness over you when you are involved in it.
And not absent from your Lord is any [part] of an atom's weight within the earth or within the heaven
or [anything] smaller than that or greater, but that it is in a clear register. Yunus 61
