Dawn has two types: the false dawn - which the Arabs call the tail of the deer - and it is the whiteness that appears in the sky lengthwise followed by darkness. The true dawn: which is the whiteness that spreads in the horizon. With the rising of the false dawn, it is not forbidden for the fasting person to eat until the true dawn rises; as the Prophet (peace be upon him) said: "Let not the call of Bilal deceive you regarding your pre-dawn meal, nor the whiteness of the horizon that extends like this until it spreads like this," and Hamad illustrated with his hands saying: "meaning horizontally." In Sahih Muslim 2: 770, and in another narration: "Let not the call of Bilal prevent any of you from having his pre-dawn meal, for he calls to awaken your sleeping ones and to bring back your standing ones. He said: And it is not that he should say - meaning the morning - like this, or he said: like this, but until he says: like this and like this, meaning lengthwise, but like this means widthwise," in Sahih Ibn Khuzaymah 3: 210, and others. See: Al-Mabsut 1: 141, and the Indian Fatwas 1: 194.
