One of the most important aspects of Islam is belief in the day of judgement (Qiyama) which emphasises the importance of accountability.
It is mentioned repeatedly in the Qur’an under various names including the Day of Accountability, the Day of Resurrection, the Hour, and the Last Day. Each of the names highlighting an aspect of accountability.


Verse 30 in chapter 3 describes what will occur on that day:

“On the day when every soul will be confronted with all the good it has done, and all the evil it has done, it will wish there were a great distance between it and its evil. But Allah cautions you (to fear) Him. And Allah is full of kindness to those that serve Him. 30:3”

Our happiness on this earth depends on this belief as it reminds us of the consequence of our actions. We therefore realise that our deeds, behaviour, thoughts, words and morals from the most important to the most insignificant have a beginning and an end just like human life. They do not end after the end of life on earth but remain to be accounted on the last day. This is why belief in Qiyama is considered an essential requirement for happiness (contentment)
