I asked `Ali (رضي الله عنه) about the nafl prayers of the Prophet (ﷺ) during the day. He said: You are not able for that. We said: Tell us and we will do as much of it as we can, He said: When the Messenger of Allah (ﷺ) prayed Fajr, he would wait until the sun would rise from there, meaning in the east, as high as it is at the time of `Asr there, meaning in the west. Then he would get up and pray two rak`ahs. Then he would wait until the sun rose as high there, meaning in the east, as it is at the time of Zuhr there, meaning in the west; then he would pray four rak`ahs, and four before Zuhr when the sun passed the meridian, and four afterwards, and four before ‘Asr, He would separate each two rak’ahs with salams upon the angels who are close to Allah, the Prophets, the believers and the Muslims who follow them. `Ali (رضي الله عنه) said: That is sixteen rak`ahs which the Prophet (ﷺ) offered as nafl prayers during the day, but there are very few who offer them regularly. Wakee’ narrated; my father said: Habeeb bin Abi Thabit said to Abu Ishaq when he narrated this to him: O Abu Ishaq, this hadeeth of yours is worth this mosque filled with gold.
