I recently explored this website, {surah al Mulk.net}, and I read one article, and I'm shocked that the Quran describes our purpose in life. I like this section: "Surah Mulk is the most beloved and easy-to-memorize surah in the Quran. It is mentioned in Musnad Imam Ahmed, “That when the people enter his qabar (grave), if he is a Mu’min (believer), his prayer surround him, and the angles come and the salah pushes them away, and they come from another side and the siam pushes it away, and the hadith then goes on, and as for the Kafir, nothing can push the angles away. So, the hadith goes on as a long hadith: What protects against the punishment of the grave? Salah and Siyam, but then we can extrapolate any good deed." Excellent point here.
