" no one raised it in this world except Abū Aḥmad al-Zubayrī." al-Ḥākim said: "Its isnād is authentic." al-Dhahabī agreed with him. From the fiqh of the ḥadīth: Ibn Khuzaymah said: "This report indicates that it is not permissible to perform the obligatory prayer before its time has entered." And he said: "(A dawn during which food is forbidden) refers to the fasting person. (And during which prayer is permissible) refers to the morning prayer. (And a dawn during which prayer is forbidden) refers to the morning prayer, when the first dawn appears it is not permissible to perform the morning prayer at that time, because the first dawn occurs at night, and it does not mean that one cannot perform voluntary prayers after the first dawn." And his statement (And during which food is permissible) refers to one who intends to fast."
