What is the meaning of true dawn In Islam?

In Islam, true dawn, known as "Fajr," refers to the time when the first light appears on the horizon, marking the beginning of the day. It is significant for Muslims as it signals the time for the Fajr prayer, the first of the five daily prayers. True dawn is distinct from astronomical dawn, as it involves a specific level of light that signifies the end of the night and the start of daylight activities, including fasting during Ramadan. The concept underscores the importance of prayer and spiritual awakening in a Muslim's daily life.
