The Prophet (ﷺ) offered the noon prayer in time of danger. Some of the people formed a row behind him and others arrayed themselves against the enemy. He led them in two rak'ahs and then he uttered the salutation. Then those who were with him went away and took the position of their companions before the enemy. Then they came and prayed behind him. He led them in two rak'ahs and uttered the salutation. Thus the Messenger of Allah (ﷺ) offered four rak'ahs and his companions offered two rak'ahs.

Al-Hasan used to give legal verdict on the authority of this tradition.

Abu Dawud said: This will be so in the sunset prayer. The imam will offer six rak'ahs and the people three rak'ahs.

Abu Dawud said: Yahya b. Abi Kathir narrated from Abu Salamah from Jabir from the Prophet (ﷺ) something similar. Sulaiman al-Yashkuri reported it from the Prophet (ﷺ) in like manner.

The Messenger of Allah (ﷺ) sent me to Khalid b. Sufyan al-Hudhail. This was towards 'Uranah and 'Arafat. He (the Prophet) said: Go and kill him. I saw him when the time of the afternoon prayer had come. I said: I am afraid if a fight takes place between me and him (Khalid b. Sufyan), that might delay the prayer. I proceeded walking towards him while I was praying by making a sign. When I reached near him, he said to me: Who are you ? I replied: A man from the Arabs; it came to me that you were gathering (any army) for this man (i.e. Prophet). Hence I came to you in connection with this matter. He said: I am (engaged) in this (work). I then walked along with him for a while ; when it became convenient for me, I dominated him with my sword until he became cold (dead).

The Prophet (ﷺ) as saying: If anyone prays in a day and a night twelve rak'ahs voluntarily (supererogatory prayer), a house will be built from him in Paradise on account of these (rak'ahs).

I asked A'ishah about the voluntary prayers offered by the Messenger of Allah (ﷺ). She replied: Before the noon prayer he would pray four rak'ahs in my house, then go out and lead the people in prayer, then return to my house and pray two rak'ahs. He would lead the people in the sunset prayer, then return to my house and pray two rak'ahs. Then he would lead the people in the night prayer, and enter my house and pray two rak'ahs. He would pray nine rak'ahs during the night, including witr (prayer). At night he would pray for a long time standing and for a long time sitting. When he recited the Qur'an while standing, he would bow and prostrate himself from the standing position, and when he recited while sitting, he would bow and prostrate himself from the sitting position, and when dawn came he prayed two rak'ahs, then he would come out and lead the people in the dawn prayer.

The Messenger of Allah (ﷺ) would pray two rak'ahs before and two after the noon prayer, two after the sunset prayer in his house, and two after the night prayer. He would not pray afte the Friday prayer till he departed. He would then pray two rak'ahs.

The Prophet (ﷺ) never omitted four rak'ahs before the noon prayer, and two rak'ahs before the dawn prayer.

The Messenger of Allah (ﷺ) was more particular about observing the supererogatory rak'ahs before the dawn prayer than about observing any of the other supererogatory prayers.
