The Quran consistently presents the heavens as a testament to Allah's creative might. Allah is described as the One who made the earth a bed [spread out and the sky a ceiling]. This imagery emphasizes a perfectly designed habitat for humanity, with the sky acting as a protective dome. Elaborating on this, the Quran states, We made the sky a protected ceiling. Tafsir al-Jalalayn explains this as being "preserved from collapsing," highlighting Allah's continuous maintenance of the cosmos. Ibn Kathir further clarifies that this protection guards against "anything reaching it," whether literally or figuratively, referring to spiritual threats like devils.

The creation of the heavens is not a whimsical act, as Allah declares, 21:16 and aimlessly. Instead, it is a purposeful act, intended to manifest divine power and benefit creation. This purposeful design extends to the structure of the heavens, as Allah states He 2:29. This concept of seven heavens is reiterated in other verses, such as He constructed it. He raised its ceiling and proportioned it, showing an ordered, multi-tiered structure. Ma'arif-ul-Quran notes that this refutes older astronomical conjectures of nine heavens, aligning with the Quran's unique cosmological assertions. These heavens are further adorned, with Allah stating, 15:16, and We have certainly beautified the nearest heaven with stars. These celestial bodies are not merely aesthetic; they serve practical purposes and are integral to the cosmos.

Beyond its physical structure, Al-Samāʾ underscores Allah's absolute control and comprehensive knowledge. The heavens and earth remain standing by His command, demonstrating a continuous divine administration rather than a one-time creation. This divine control is intertwined with Allah's omniscience, as nothing is hidden from Allah on the earth or in the heaven and 14:38. The Prophet Muhammad (peace be upon him) affirmed this, saying, 21:4.

This divine knowledge extends to every minute detail, including 34:2. Ibn Kathir expounds that this includes "the number of raindrops that sink into the depths of the earth, and the seeds that have been sown... and what ascends into it, i.e., righteous deeds and other things." This comprehensive knowledge reaffirms that Allah's governance is absolute and flawless, overseeing every aspect of existence in both the seen and unseen realms.

The heavens play a crucial role in sustaining life on Earth, primarily through the sending down of rain. Allah is described as the One who 2:22. This connection between the sky, rain, and sustenance is a recurring theme. The Quran also states, 51:22. Tafsir al-Jalalayn interprets this as rain, which is a source of provision.

The mechanism involves winds, which Allah sends forth as fertilizing. Ibn Kathir explains these winds "fertilize the clouds so that they give rain, and fertilize the trees so that they open their leaves and blossoms." This intricate process transforms salty sea water into potable freshwater, a clear sign of divine wisdom and mercy. As Allah reminds, if you try to count the blessings of Allah, never will you be able to count them, emphasizing the countless benefits derived from this celestial provision. The purpose of presenting these signs is to invite humanity to reflect upon them, as truly therein are signs for every patient, thankful (person), leading to gratitude and deeper faith.

The heavens are not merely physical entities but are also associated with spiritual realities and divine interactions. The celestial realm is the source of divine revelation, as the Quran states, We have revealed to you the Book... that you may bring forth mankind from darkness into light by their Lord's leave. The Quran itself is termed "the Remembrance" (Al-Dhikr), which Allah promises to protect, saying, Verily it is We Who have revealed the Remembrance and assuredly We will preserve it. Ibn Kathir narrates the story of a Jewish scribe who, after attempting to alter manuscripts of the Torah and Injil successfully, found it impossible to tamper with the Quran, leading him to accept Islam. This illustrates the Quran's divine protection, emanating from the heavens.

The heavens are also inhabited by angels, who act strictly under His command. Their constant worship and obedience contrast sharply with human disobedience. Furthermore, the heavens are guarded against devils. Allah states, 67:5 them what is thrown at the devils]. The Quran also describes how Jinns tried to “reach the heaven but found it filled with powerful guards and burning flames”. A Hadith narrated by Ibn `Abbas vividly illustrates this, recounting how devils attempting to eavesdrop on celestial news were struck by flames, leading them to discover the Prophet Muhammad (peace be upon him)'s message Bukhari 65:441. This highlights the unseen activities and the protection of divine knowledge in the heavens.

For the righteous, the heavens represent a path to divine favor. While the physical gates of heaven will not be opened for those who disbelieve 7:40, for believers, there is hope. The deeds of believers are described as ascending to heaven, akin to a goodly tree... whose branches (reach) to the sky, signifying acceptance and blessing. The Prophet Muhammad (peace be upon him) taught a prayer for steadfastness, acknowledging that guidance and straying are from Allah alone, a prayer often recited by the companions, "O You Who changes the hearts, make our hearts firm on Your religion" (Ibn Kathir on 3:8). This devotion reflects the spiritual aspiration towards the heavenly realm.

The present order of the heavens is not eternal; it will undergo cataclysmic changes on the Day of Judgment, serving as a powerful reminder of Allah's absolute power and the impending accountability. The Quran describes that day when We will fold the heaven like the folding of a [written sheet for the records]. This imagery is further elaborated in Hadith, where the Prophet Muhammad (peace be upon him) said that Allah will seize the Earth and the heavens will be in His Right Hand (Bukhari, related to 21:104).

Other verses depict the sky splitting apart: When the sky breaks apart, When the sky has split [open], 55:37, and the heaven will split [open, for that Day it is infirm]. These descriptions, like the sky will be like murky oil, illustrate the profound disruption and transformation of the cosmos. These events are not aimless but are part of Allah's comprehensive plan for resurrection and reckoning. As Allah initiated creation, so too will He repeat it, a promise binding upon Him 21:104. This transformative power serves as a clear warning to humanity that all will return to Allah for judgment.

The concept of Al-Samāʾ in Islam is thus an expansive one, encompassing the physical sky, the multilayered heavens, and their intricate connection to divine power, human sustenance, spiritual guidance, and the ultimate destiny of all creation. It serves as a constant and undeniable sign, inviting reflection and inspiring gratitude, fear, and hope in the boundless majesty of Allah.
