What is better than what they accumulate, and is mentioned in several places in the Holy Quran?

What is asked about in the verses is mercy, and it may be accompanied by forgiveness and Allah's grace. In Surah Al Imran:157, those killed in the way of Allah and those who die attain forgiveness and mercy from Allah, which is better than what they accumulate. In Surah Yunus:58, it is commanded to rejoice in Allah's grace and mercy because it is better than what they accumulate. In Surah Az-Zukhruf:32, only mercy is mentioned, and that the mercy of your Lord is better than what they accumulate.
