Narrated by al-Husayn ibn Sa’id from al-Nadr from ‘Asim ibn Humayd from Abu Basir al-Makfuf, who said: I asked Abu Abdillah عليه السلام about the fasting person; when does food become forbidden for him? Imam عليه السلام said: "When the dawn is like the white Coptic garment." I asked: "Then when does the prayer become permissible?" Imam عليه السلام said: "When it is like that." I asked: "Am I not within the time (of prayer) from that moment until the sun rises?" Imam عليه السلام said: "No, we only count that as the prayer of children." Then Imam عليه السلام said: "Indeed, it was not commendable for a man to pray in the mosque and then return to wake up his family and children"
