I heard Ibn 'Abbas saying that the Messenger of Allah (ﷺ) observed thirteen rak'ahs at night.

O Allah, to Thee be the praise Thou art the light of the heavens and the earth. To Thee be the praise; Thou art the Supporter of the heavens and the earth. To Thee be the praise; Thou art the Lord of the heavens and the earth and whatever is therein. Thou art the Truth; Thy promise is True, the meeting with Thee is True. Paradise is true, Hell is true, the Hour is true. O Allah, I submit to Thee; affirm my faith in Thee; repose my trust in Thee, and I return to Thee for repentance; by Thy help I have disputed; and to Thee I have come for decision, so forgive me my earlier and later sins, the sins that I committed in secret and openly. Thou art my God. There is no god but Thee.

I turn my face (up to Thee), I am the first of the believers; and when he raised his head from ruku' he said: Allah listened to him who praised Him; O our Lord, praise be to Thee; and he said: He shaped (man) and how fine is his shape? And he (the narrator) said: When he pronounced salutation he said: O Allah, forgive me my earlier (sins), to the end of the hadith; and he did not say it between the Tashahhud and salutation (as mentioned above).

Allah has prescribed the prayer by the tongue of your Apostle (ﷺ) as two rak'ahs for the traveller, four for the resident, and one in danger.

A hadith like this has been narrated by Abu Qatada with the same chain of transmitters.

I heard 'Abd al-Rahman as saying; 'Uthman led us four rak'ahs of prayer at Mina. It was reported to Abdullah b. Mas'ud and he recited:" Surely we are Allah's and to Him shall we return," and then said: I prayed with the Messenger of Allah (ﷺ) at Mina two rak'ahs of prayer. I prayed along with Abu Bakr al-Siddiq two rak'ahs of prayer at Mina. I prayed along with 'Umar b. Khattab two rak'ahs of prayer at Mina. I wish I had my share of the two rak'ahs acceptable (to God) for the four rak'ahs.

A hadith like this has been reported by A'mash with the same chain of transmitters.

I prayed with the Messenger of Allah (ﷺ) two rak'ahs and most of them offered two rak'ahs only in Mina, while the people felt secure.

He who did it, i. e. the Messenger of Allah (ﷺ), was better than I.

Ibn 'Umar reported that the Apostle (ﷺ) used to pray on (the back of) his camel in whatever direction it took him.

I saw the Messenger of Allah (ﷺ) praying (Nafl prayer) on a donkey's back while his face was turned towards Khaibar.

'Abdullah b. Dinar reported on the authority of Ibn 'Umar that the Messenger of Allah (ﷺ) used to observe prayer on his ride (no matter) in which direction it had its face turned. 'Abdullah b. Dinar said that Ibn 'Umar used to do like that.

'Abdullah b. 'Amir b. Rabi'a has reported on the authority of his father that he had seen the Messenger of Allah (ﷺ) observing Nafl player at night on a journey on the back of his ride in whichever direction it turned its face.

Anas reported that when the Messenger of Allah (ﷺ) had to set out on a journey hurriedly, he delayed the noon prayer to the earlier time for the afternoon prayer, and then he would combine them, and he would delay the sunset prayer to the time when the twilight would disappear and then combine it with the 'Isha' prayer.

The Messenger of Allah (ﷺ) observed the noon and afternoon prayers together in Medina without being in a state of fear or in a state of journey. (Abu Zubair said: I asked Sa'id [one of the narrators] why he did that. He said: I asked Ibn 'Abbas as you have asked me, and he replied that he [the Holy Prophet] wanted that no one among his Ummah should be put to [unnecessary] hardship.)

" I said to Ibn 'Abbas: What prompted him to do that? He said: So that his (Prophet's) Ummah should not be put to (unnecessary) hardship." And in the hadith transmitted by Mu'awiya (the words are):" It was said to Ibn 'Abbas: What did he intend thereby? He said he wanted that his Ummah should not be put to unnecessary hardship."

None of you should give a share to Satan out of your self. He should not deem that it is necessary for him to turn but to the right only (after prayer). I saw the Messenger of Allah (ﷺ) turning to the left.

The Apostle of Allah (ﷺ) used to turn to the right (at the end of the prayer).

When we prayed behind the Messenger of Allah (ﷺ) we cherished to be on his right side so that his face would turn towards us (at the end of the prayer), and he (the narrator) said: I heard him say: O my Lord! save me from Thy torment on the Day when Thoil, wouldst raise or gather Thy servants.

When the prayer commences then there is no prayer (valid), but the obligatory prayer. This hadith has been narrated by Warqa' with the same chain of transmitters.
