Machine translationRead the Arabic original
Question:
He says: Honorable Shaykh, may Allah grant you success. He says: How is the first, middle, and last third of the night calculated? Is it from the setting of the sun, or after the 'Isha' prayer?
Answer:
No, from the setting of the sun. The night begins from the setting of the sun until the appearance of the dawn. Divide the time between the setting of the sun and the appearance of the dawn into three parts, and it will become clear to you.
