It is narrated from Hazrat Nafi' that if Hazrat Ibn Umar (may Allah be pleased with them both) missed the prayer of Arafat with the Imam, he would perform the Zuhr and Asr prayers in his saddle.

Ibrahim says that if you perform prayer in your litter at Arafat, then perform each prayer at its prescribed time, and for each prayer, also say the adhan and the iqamah.

Hazrat Ata says that if you are performing prayer in your saddle, then it is up to you: if you wish, you may combine both prayers, and if you wish, you may perform each prayer at its own time.

Hazrat Ibn Tawoos states that my respected father never performed prayer with the Imam in Arafat, and he would combine both prayers and offer optional prayers between them, and he would do so from the place of Jund until he reached Makkah Mukarramah.

Ibrahim says that perform every prayer at its appointed time.
