Asim bin Damrah says that once we asked Sayyiduna Ali (may Allah be pleased with him) how the Prophet (peace and blessings be upon him) used to offer voluntary prayers during the day. He replied: "You do not have the strength to pray as he did." We said: "Please tell us, we will try to act upon it according to our strength and ability." He said: "The Prophet (peace and blessings be upon him) would offer the Fajr prayer and then wait for a while. When the sun would rise in the east to the extent that it is in the west after the Asr prayer, he would stand and offer two rak'ahs of prayer. Then he would wait for a while, and when the sun would rise in the east to the extent that it is in the west after the Zuhr prayer, he would stand and offer four rak'ahs of prayer. Then, after the sun had declined, he would offer four rak'ahs before Zuhr, two rak'ahs after Zuhr, and four rak'ahs before Asr. In every two rak'ahs, he would recite words of peace (the tashahhud) for the close angels, the noble prophets (peace be upon them), and the Muslims and believers who follow them. In this way, the voluntary prayers of the Prophet (peace and blessings be upon him) during the whole day amounted to sixteen rak'ahs, but very few are those who are consistent in them." After narrating this hadith, Habib bin Abi Thabit said: "O Abu Ishaq! This hadith of yours is equal to this mosque being filled with gold."
