"Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?" (Quran 21:30)

 "Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?" (Quran 21:30)

In this verse, Allah (SWT) is questioning the disbelievers whether they have not reflected on the creation of the heavens and the earth. Allah (SWT) reminds the disbelievers that the heavens and the earth were once a single entity, and it was He who separated them. This statement is a reference to the cosmological concept of the Big Bang, which modern science also confirms as the origin of the universe.

Allah (SWT) then draws attention to the fact that water is the source of all living things on earth. This is a profound statement that highlights the importance of water as a crucial element for all living beings. Without water, life on earth would not be possible. This fact is emphasized throughout the Quran in various verses.

The verse ends with a rhetorical question, asking whether the disbelievers will not believe after pondering on these facts. This is a common theme in the Quran, where Allah (SWT) calls on people to reflect on His creation and recognize His power and wisdom. It is through such contemplation and reflection that people can come to a deeper understanding of their purpose in life and their relationship with Allah (SWT).

This verse from Surah Al-Anbiya' (The Prophets) highlights the concept of Tawheed (Oneness of Allah) and His power as the Creator. Allah questions the disbelievers if they have not considered that the heavens and the earth were a joined entity, meaning that they were together before being separated. This refers to the Islamic belief that Allah created the universe from nothing and then separated the heavens and the earth from each other.

Allah further highlights His power as the Creator by stating that He made from water every living thing. This is a reference to the scientific fact that water is essential for all forms of life on earth. Allah is reminding the disbelievers that He is the One who provides life to everything and that they should not attribute this power to anyone or anything else.

The verse ends with a rhetorical question, "Then will they not believe?" This question serves as a reminder to the disbelievers that they should recognize Allah's power as the Creator and believe in Him. It also emphasizes the importance of reflecting on the signs of Allah's creation as a means of strengthening one's faith.
