Dream - The Apocalypse is a certainty that will happen. Where the world and everything in it will be destroyed, including living creatures within it. Regarding the occurrence of the Apocalypse, Allah SWT has already given signs through the Quran and the hadiths of the Prophet. However, it is not mentioned in detail when exactly the Apocalypse will occur. One of the hadiths that explains the signs of the Apocalypse is the drying up of the Euphrates River and the emergence of a mountain of gold. According to scientific research, since 2003, the Tigris and Euphrates River basins in Turkey, Syria, Iraq, and Iran have lost 117 million acre-feet (144 cubic kilometers) of freshwater.

Rasulullah saw said, "The Day of Judgment will not occur until the Euphrates river dries up and the mountain of gold emerges. People will then kill each other to claim it. Out of every hundred people, ninety-nine will be killed. Each person will say, 'Hopefully, I am the one who survives.'" (HR Muslim) Regarding the emergence of the mountain of gold, many say that it refers to petroleum. This is because petroleum has often been referred to as black gold.

Although that's the case, if we look back at the hadith, it mentions 'mountain of gold'. However, crude oil is not gold. The Prophet Muhammad informed that when the Euphrates River dries up, the mountain of gold will be visible to humans. On the other hand, crude oil needs to be extracted from the earth using mining equipment. In this context, the Prophet Muhammad only mentioned the Euphrates River without mentioning other rivers or seas. Crude oil can also be extracted from the depths of the sea.

Not only that, the Prophet Muhammad also informed that humans will kill each other and fight over this treasure. As we know, when oil reserves are found, there is a desire to possess them by those in power. However, the Prophet Muhammad apparently forbade anyone from taking the gold mountain when it appears. As the Prophet Muhammad said: "Soon the Euphrates River will dry up and the gold mountain will appear. Whoever finds it, do not take even a little bit."

Then, in another hadith it is explained as follows: " ... then there appeared a treasure in the form of gold ..." (HR. Bukhari no. 7119 and Muslim no. 2894) This prohibition certainly has its own reasons. This is explained by Al-Hafidz Ibnu Hajar Al-Asqalani, that the prohibition of taking gold from the mountain is to prevent chaos and killing among humans.

The Euphrates River cuts through the Taurus Mountains, passing through Syria in the city of Jarablus, then through Iraq in the city of al-Bukmal, and meets the Tigris River in al-Qumah, which flows into the Arabian Gulf. There are several factors that cause the Euphrates River to dry up. The Ataturk Dam, located in Turkey, is one of the 22 dams along the river that provide irrigation and hydroelectric power. As a result, the downstream flow of the river has less volume.

Then, global climate change also becomes a factor causing the drying up of the Euphrates River. Where rainfall has decreased around the river flow. In addition, warm temperatures also cause evaporation to occur because the water surface continues to decrease. With such conditions, it is feared that the Euphrates River will completely dry up by 2040. However, the Euphrates River is the most important river in human history along with the Tigris River.
