(1) باب أَبْوَابِ مَوَاقِيتِ الصَّلاَةِ
It was narrated from Sulaiman bin Buraidah that his father said:
"A man came to the Prophet and asked him about the times of the prayer. He said: 'Pray with us for two days.' When the sun passed its zenith he commanded Bilal to call the Adhan, then he commanded him to give the Iqamah for Zuhr; then he commanded him to give the Iqamah for 'Asr when the sun was high and clearly white. Then he commanded him to give the Iqamah for Maghrib when the sun had set; then he commanded him to give the Iqamah for 'Isha' when the red afterglow had disappeared; then he commanded him to give the Iqamah for Fajr when dawn came. On the following day he commanded him to give the Adhan for Zuhr when the extreme heat had passed and it had cooled down; then he prayed 'Asr when the sun was still high, but he delayed it more than he had done the day before; then he prayed Maghrib before the red afterglow disappeared; he prayed 'Isha' when one-third of the night had passed; and he prayed Fajr at the time when it was already light. Then he said: 'Where is the one who was asking about the times of Prayer?' The man said: 'Here I am, O Messenger of Allah.' He said: 'The times of your prayer are between the times you have seen.'"
