The Quran repeatedly underscores the universality of death, affirming that Every soul will taste death and Every soul will taste death. Then to Us will you be returned. This divine decree applies to all beings on Earth, as Everyone upon the earth will perish, with only the glorious Countenance of Allah remaining full of majesty, full of honor. Tafsir Ibn Kathir explains that this means all residents of Earth and heavens will eventually perish, and only Allah, the Ever-Living, will remain. The phrase "the Face of your Lord" (wajh Rabbika) is interpreted by some exegetes, like those in Ma'arif-ul-Quran, to mean "the Being of Allah," emphasizing His self-subsisting and eternal nature.

The Quran clarifies that there is no escape from this appointed end, even if one were within towers of lofty construction. Imam Ibn Kathir cites the story of Khalid bin Al-Walid, known as "Saifullah" (Sword of Allah), who yearned for martyrdom in battle but ultimately died in his bed, illustrating that Allah's decree of life and death is final and cannot be averted by human efforts or fortifications. Death is not a calamity to be feared but an inevitable passage, and fear of it should not hinder one from fulfilling divine commands, such as migration for the sake of Allah.

The process of death involves the departure of the soul from the body, an event described as "the intoxication of death" “which will bring the truth”. Tafsir Ma'arif-ul-Quran notes that the term "sakrat-ul-maut" refers to the agony and stupor a dying person experiences, a reality affirmed by the Prophet Muhammad ﷺ, who, while in his own final moments, wiped sweat from his face and said, "Glory be to Allah! Verily, death has its stupor" Sahih al-Bukhari 81:99.

Angels play a crucial role in this transition. For those who disbelieved and wronged themselves, the angels take their souls while striking their faces and their backs, telling them to Taste the punishment of the Burning Fire. Ibn Jurayj and Ibn `Abbas explain that this punishment can be observed during the Battle of Badr, where angels smote the faces and rear ends of disbelievers, or generally refers to the unseen torment in the grave (Barzakh). Conversely, for the righteous and pure, angels greet them with "Peace be upon you. Enter Paradise for what you used to do" the ones whom the angels take in death, [being good and pur...](16:32). This stark contrast highlights the immediate consequence of one's worldly deeds.

Death signifies the cessation of earthly actions and the commencement of accountability. The Quran states that to Us you will be returned and Then to Us will you be returned, emphasizing the ultimate reckoning before Allah. On the Day of Judgment, every soul will come forth along with a driver and a witness. Tafsir Ibn Kathir and Ma'arif-ul-Quran interpret "driver" and "witness" as two angels: one to drive the soul to the gathering place and another to testify about its deeds.

The deeds of individuals, whether good or evil, will be meticulously weighed on scales of justice on the Day of Judgment. Even an act as small as the weight of a mustard seed will be brought forth. According to a Hadith, a balance of enormous size will weigh all deeds, ensuring no injustice. A powerful illustration from Aisha describes a man whose good and bad deeds were weighed against his punishment of slaves. If his punishment was less than deserved, it would count in his favor; if more, he would be held accountable (Sahih al-Bukhari 21:47, as cited by Ibn Kathir and Ma'arif-ul-Quran). This signifies the meticulous divine justice that awaits every soul.

The journey beyond death includes the intermediate realm of Barzakh, a barrier between this world and the Hereafter, where souls await resurrection (and in front of them is Barzakh until the Day when they will be resurrected). This is a period of continuous punishment for the wrongdoers until the Day of Resurrection, as explained by Muhammad bin Ka`b and Abu Sakhr. On the Day of Judgment, the Trumpet will be blown (Naqur) twice, as described in Tafsir Ma'arif-ul-Quran: the first blast causing all to swoon and die, and the second bringing forth resurrection Then, when the Trumpet will be blown for the first time.

Given death's certainty, Islam encourages a life of constant preparation. The Quran commands believers to 15:99. Tafsir Ibn Kathir clarifies that "certainty" here refers to death, emphasizing that acts of worship remain obligatory as long as one is of sound mind. This rejects any Sufi interpretation that "certainty" implies a level of spiritual knowing that absolves one of religious duties.

The transient nature of this world and the eternal reality of the Hereafter are consistently highlighted. The Quran describes this worldly life as nothing but an amusement and play, and the Last Abode is the real life indeed. This perspective encourages believers to prioritize deeds that yield eternal reward over fleeting worldly gains. The Prophet Muhammad ﷺ taught that a person's true wealth is what they have spent in Allah's way, eaten, or worn out, while everything else will be left for others Muslim 102:2. This reinforces the importance of righteous actions and charity during one's lifetime.

The Quran draws a clear distinction between the fate of believers and disbelievers after death. Those whom the angels take [in death while wronging themselves] are questioned about their state and their failure to emigrate for Allah's cause, with their refuge being Hell. Conversely, those whom the angels take in death, [being good and pure] are welcomed into Paradise.

The disbelievers often express astonishment at the concept of resurrection, questioning, "When I have died, am I going to be brought forth alive?" 19:66. Allah refutes this by reminding them of His power to originate creation from nothing and His ease in repeating it [Does not man remember that We created him before, while he was nothing?](19:67 as cited by Tafsir Ibn Kathir). Their denial stems from their heedlessness and focus on temporary worldly pleasures, which they ultimately regret when facing divine punishment. In the Hereafter, they will desperately wish to return to do good, but their plea will be rejected, as it is merely a word that he speaks without sincerity.

For believers, death is a gateway to eternal bliss. Paradise is described as a place where they will not taste death therein except the first death, being protected from the punishment of Hellfire. They will reside in a place of security, enjoying abundant fruits, flowing springs, and purified mates “in peace and security”. The Prophet Muhammad ﷺ described death being brought forth as a ram between Paradise and Hell and then slaughtered, after which it is announced: "O people of Paradise, it is eternal, no more death; and O people of Hell, it is eternal, no more death" Sahih al-Bukhari 81:137. This emphasizes the permanence of the afterlife and the ultimate reward for the righteous.

Death in Islam is thus profoundly integrated into a comprehensive worldview that connects life in this world with the eternal journey beyond. It serves as a constant reminder of divine power, human accountability, and the importance of living a life of conscious submission and striving for righteousness. From the moment of creation, through life's trials, to the final moment of departure, and the subsequent reckoning and reward, death is a pivotal concept that shapes Islamic theology, ethics, and law, directing humanity towards a purposeful existence oriented towards their ultimate return to Allah.
