Combining means that it is a slow process and gradually changes from day to night. This phenomenon can only occur on objects with a spherical shape, if the earth is flat, then the earth can not change from day to night and from night to day. The following is another quote from the Qur'an of Islam, chapter 39, verse 5: "He created the heavens and the earth. He made the night to cover the day, and He made the day to cover the night; To connect with سَّمَالْأَرْضَ بِالْحَقِّ ۖ, sign up for Facebook today. In Arabic, the word (Kawara) يُكَوِّرُ means overlapping or overlapping, for example, a scarf around the head. Day and night cycles can only occur in round situations. The planet does not mean round like a ship, it is spherical. In Al-Quran, chapter 79, verse 30, it says, "Then He flattened the earth." ْأَرْضَالْأَرْضَ بَعْدَ بَعْدَلِكَ ِكَاهَا - 79:30 The Arabic word for egg is called (dahaha) ដែលاهَا, which literally refers to the rolling of an egg (the movement of an egg by rolling). The shape of the roll changes the position of an egg, revealing the topography of the earth as it stretches. Al Qur'an, therefore, gives the most accurate indication of the Earth's topography, which is flat (does not refer to the whole shape of the Earth).
