Kuraib, the freed slave of Ibn Abbas (RA) , narrated from Usama bin Zaid (RA) that he had heard him saying: Allah's Messenger (ﷺ) proceeded from 'Arafa, and as he approached the creek of a hill, he got down (from his camel) and urinated, and then performed a light ablution. I said to him: Prayer, whereupon he said: The prayer awaits you (at Muzdalifa). So he rode again, and as he came to Muzdalifa, he got down and performed ablution well. Then Iqama was pronounced for prayer, and he observed the sunset prayer. Then every person made his camel kneel down there, and then Iqama was pronounced for 'Isha' prayer and he observed it, and he (the Holy Prophet) did not observe any prayer (either Sunan or Nawafil) in between them (He observed the Fard of sunset and 'Isha' prayers successively.)
Usama bin Zaid (RA) reported: Allah's Messenger (ﷺ) on his way back from 'Arafat got down in one of these creeks (to answer the call of nature), and after he had done that I poured water (over his hands) and said: Are you going to pray? Thereupon he said: The place of prayer is ahead of you.
Usama bin Zaid (RA) narrated: Allah's Messenger (ﷺ) was on his way back from 'Arafat and as he reached the creek (of a hillock) he got down and urinated (Usama did not say that he poured water), but said: He (the Holy Prophet) called for water and performed ablution, but it was not a thorough one. I said: Messenger of Allah, the prayer! Thereupon he said: Prayer awaits you ahead (at Muzdalifa). He then proceeded, until he reached Muzdalifa and observed sunset and 'Isha' prayers (together) there.
Kuraib reported that he asked Usama bin Zaid (RA) What did you do in the evening of 'Arafa as you rode behind Allah's Messenger (ﷺ) ? He said: We came to a valley where people generally halted their (camels) for the sunset prayer. Allah's Messenger (ﷺ) halted his camel and urinated (and he did not say that he had poured water). He then called for water and performed light ablution. I said: Messenger of Allah, the prayer! Thereupon he said: Prayer awaits you (at Muzdalifa), and he rode on until we came to Muzdalifa. Then he offered the sunset prayer and the people halted their camels at their places, and did not untie them until Iqama was pronounced for the 'Isha' prayer and he observed the prayer, and then they untied (their camels). I said: What did you do in the morning? He said: Al-Fadl bin Abbas (RA) sat behind him (the Holy Prophet) in the morning, whereas I proceeded on foot with the Quraish who had gone ahead.
Usama bin Zaid (RA) reported that when Allah's Messenger (ﷺ) came to the valley where the rich (people of Makkah) used to get down, he got down and urinated (and he did not mention about pouring water); he then called for water and performed a light ablution. I said: Messenger of Allah, the prayer. Thereupon he said: Prayer awaits you ahead.
Usama bin Zaid (RA) reported that he sat behind Allah's Messenger (ﷺ) on his ride as he came back from 'Arafa. And as he came to the valley, he halted his camel, and then went to the wilderness (to urinate). And when he came back, I poured water on him from the jug and he performed ablution, and then rode on until he came to Muzdalifa and there he combined the sunset and 'Isha' prayers.
Ibn Abbas (RA) reported that Allah's Messenger (may peace be upon, him) came back from 'Arafa and Usama (RA) was seated behind him. Usama said that he (the Holy Prophet) continued the journey in this very state until he came to Muzdalifa.
Hisham (RA) reported from his father: Usama (RA) was asked in my presence or I asked Usama bin Zaid and he rode behind Allah's Messenger (ﷺ) as he came back from 'Arafat. I said (to him): How did Allah's Messenger (ﷺ) journey as he came back from 'Arafat? Thereupon he said: He made it (his riding camel) walk at a slow speed, and when he found an open space, he made it walk briskly.
This hadith has been narrated on the authority of 'Urwa with the same chain of transmitters. And in the hadith narrated by Humaid there is an addition (of these words): "Hisham said: Al-nass (speed of camel) is faster than al-'anaq."
Abdullah bin Yazid al-Khatmi reported on the authority of Abu Ayyub (RA) that he prayed the sunset and 'Isha' prayers (together) at Muzdalifa in the company of Allah's Messenger (ﷺ) on the occasion of the Farewell Pilgrimage.
Ubaidullah bin 'Abdullah bin 'Umar reported on the authority of his father (RA) that Allah's Messenger (ﷺ) combined the sunset and 'Isha' prayers at Muzdalifa and there was no prostration (i. e. any rak'ahs of Sunan or Nawafil prayers) in between them. He observed three rak'ahs of the sunset prayer and two rak'ahs of the 'Isha' prayer, and 'Abdullah (b. 'Umar) observed the prayers in this very manner (at Muzdalifa) until he met his Lord.
Sa'id bin Jubair reported that he observed the sunset and 'Isha' prayers at Muzdalifa with (one) iqama. He narrated on the authority of Ibn 'Umar (RA) that he observed prayers like this. And Ibn 'Umar (RA) narrated that Allah's Apostle (ﷺ) did like this.
Ibn 'Umar reported that Allah's Messenger (ﷺ) combined the sunset and 'Isha ' prayers at Muzdalifa. He observed three rak'ahs of the sunset prayer and two rak'ahs of the 'Isha' prayer with one Iqama.
Sa'id bin Jubair reported: We came back along with Ibn 'Umar till we reached Muzdalifa. There he led us in the sunset and 'Isha' prayers with one iqama and we then proceeded and he said: This is how Allah's Messenger (ﷺ) led us in prayer at this place.
