The Quran lays an undeniable foundation for the belief in Resurrection by declaring that Allah is the 2:28 and unto Allah you will be gathered.

The concept of Resurrection is integral to the entire divine scheme, emphasizing accountability. As Allah states, “to Allah all matters are returned”, signifying that ultimately, all deeds will be judged. Tafsir al-Jalalayn explains that this return is for Allah to requite individuals according to their deeds. Ibn Kathir clarifies that the phrase “you will be returned to Him” means that all affairs are subject to His will and just decision, making it easier for believers to obey and refrain from prohibitions.

To dispel doubts about His ability to resurrect, the Quran presents several powerful examples from history. One notable narrative is that of the man who questioned how Allah could bring a ruined township back to life. Allah then caused him to die for a hundred years; then He revived him. This man, identified by some scholars as `Uzayr (Ezra), witnessed the swift reconstitution of his donkey's bones and flesh, confirming that "Allah is over all things competent." Ibn Kathir details how this incident, alongside others, serves as a direct proof against the Jews who doubted Resurrection.

Another profound example is Prophet Abraham's plea, "My Lord, show me how You give life to the dead." Though Abraham already believed, as Allah's reply Have you not believed? indicates, his request was "only that my heart may be satisfied." Ibn Kathir notes that Abraham sought to solidify his knowledge of resurrection by witnessing it. Allah instructed him to take four birds, dismember them, place parts on separate hills, and then call them; “they will come flying to you in haste”. Ma'arif-ul-Quran explains that the birds were commanded to come running rather than flying to make the miracle even more impressive and undeniable, visually resolving all doubts about reanimation. This demonstrated that Allah's perfect power could reassemble scattered parts and infuse life, illustrating the reality of life after death.

Despite these clear signs, the Quran records the persistent denial of Resurrection by disbelievers. They scoff, 6:29, or query, When we are dust, will we indeed be [brought into a new creation?]. Such skepticism is depicted as a fundamental misunderstanding of Allah's creative power. The Quran challenges their logic: 19:67, implying that initial creation from nothing is a greater marvel than re-creation.

Ibn Kathir notes that disbelievers are "deaf and dumb in darkness" to these truths, their hearts being veiled. Their denial stems from ignorance, as they do not possess sound comprehension or fair judgment. However, the Quran asserts that 27:87, 50:20), which will herald the emergence from graves. Tafsir al-Jalalayn clarifies that "on the Day He says to a thing 'Be' and it is" refers to the Day of Resurrection, when creatures are commanded to rise.

The Day of Resurrection is invariably linked with the Day of Judgment, where every soul will be held accountable. The Quran states, 19:95. This emphasizes individual accountability without partners or intercessors. On this day, Allah 19:85, while wrongdoers will face severe torment.

The Hadith literature provides further details about this terrifying day. Abu Huraira narrates that the Prophet ﷺ said that people will be gathered on the Day of Resurrection to such an extent that "the sweat will reach up to the middle of the ears." Sahih al-Bukhari 0:0. During this immense distress, people will seek intercession from prophets, beginning with Adam, then Noah, Abraham, Moses, Jesus, and finally Muhammad ﷺ (Sahih al-Bukhari 60:15, 97:39). Each prophet will decline, citing a personal shortcoming, until Prophet Muhammad ﷺ is granted the right of intercession (Al-Maqam Al-Mahmud) to judge among the people.

The weighing of deeds (al-wazn) is a crucial aspect of this judgment. The Quran states, And the weighing on that day is definite. Tafsir Ibn Kathir explains that this means Allah will not wrong anyone, and even deeds "the weight of a mustard seed" will be brought to account. Hadith elaborates on this: some deeds will be given physical weight, books of deeds will be weighed, and even individuals themselves will be weighed. Abu Huraira narrates that the Prophet ﷺ said, "On the Day of Resurrection, a huge fat man will come who will not weigh, the weight of the wing of a mosquito in Allah's Sight." Sahih al-Bukhari 65:251. Conversely, the Prophet ﷺ remarked about Abdullah bin Mas`ud, "By He in Whose Hands my soul is, his legs... are heavier on the Balance than (Mount) Uhud." (Tafsir Ibn Kathir 7:9). This implies that value is not in physical size but in the significance of deeds.

The ultimate consequence of Resurrection and Judgment is entry into Paradise for the righteous and Hellfire for the disbelievers and wrongdoers. The Quran promises those who believe and do good deeds Gardens under which rivers flow, where they shall live forever, and wives purified, and approval from Allah. This approval is considered the ultimate blessing, far surpassing worldly joys.

Conversely, those who disbelieve will face a "painful torment" and "abide therein forever" (3:39, 7:36). Their wealth and offspring will not avail them against Allah. The severity of Hell is vividly described, with "boiling water to drink" and "a bed from the Jahannam, and over them there are coverings". The doors of heaven will not be opened for them, and their entry into Paradise will be as impossible as a camel entering into the eye of a needle.

A critical point of Islamic theology regarding judgment is that belief and repentance are only accepted up to a certain point. The Quran states, The day some signs of your Lord come, the believing of a person will be of no use to him who had never believed before. Hadith identifies this sign as the sun rising from the West. After this, faith and repentance will not be accepted, as they would no longer be a matter of free choice but of compelled observation.

The belief in Resurrection is not merely a theological concept but a profound ethical catalyst. It instills a deep sense of purpose and responsibility, reminding believers that Allah is All-Seer of what they do. This awareness motivates good deeds and deters from evil, even in private, because a Muslim knows that "somebody is watching him, and somebody is writing down the smallest thing he does" (Ma'arif-ul-).

The concept of a "fixed term" for death and a "determined term" for the Hereafter underscores the fleeting nature of this life and the certainty of accountability. The Prophet ﷺ's teaching that "the servant will not acquire the status of the Muttaqin until he abandons what is harmless out of fear of falling into that which is harmful" (Tafsir Ibn Kathir 2:2) highlights the proactive spiritual vigilance inspired by the belief in Resurrection. It encourages sincerity in worship and actions, as hypocrites who merely profess faith outwardly are condemned as those who "only deceive themselves".

Resurrection, therefore, transforms worldly existence into a preparatory stage for an eternal life, urging individuals to prioritize spiritual well-being and righteous conduct over fleeting material gains. This profound belief fosters patience, gratitude, and an unwavering commitment to Allah's commands, knowing that every act, whether public or private, contributes to one's ultimate destiny.

Resurrection (al-Ba'th) stands as a foundational tenet of Islam, intricately woven throughout the Quran and Sunnah. It manifests Allah's supreme power and perfect justice, illustrating a cycle of creation, death, and re-creation that culminates in a universal reckoning. The vivid Quranic narratives and prophetic teachings not only confirm the reality of a future judgment but also serve as a profound ethical framework, guiding believers to live with accountability, sincerity, and an unwavering focus on the eternal recompense. The detailed accounts of rewards and punishments underscore the ultimate significance of faith and righteous deeds in shaping one's destiny in the Hereafter.
