1203
Musnad AhmedIt was narrated from ‘Ali (رضي الله عنه) that
He was asked about the (voluntary) prayers of the Messenger of Allah (ﷺ) during the day. He said: He used to pray sixteen rak"ahs, When the sun was as high there as it is at the time of ‘Asr there, he would pray two rak’ahs. When the sun was as high there as it is at the time of Zuhr there, he would pray two rak"ahs, He would pray four rak"ahs before Zuhr and two rak"ahs after Zuhr, and he would pray four rak"ahs before ʻAsr.
