And from Husain, from Yahya bin Abi Kathir, from Hafs bin Ubaidullah bin Anas, from Anas bin Malik (Allāh be pleased with him), he narrated that

the Prophet ﷺ used to combine the prayers of Maghrib and Isha while travelling.

Husain has been corroborated by Ali bin al-Mubarak and Harb, from Yahya, from Hafs, from Hazrat Anas, that the Prophet ﷺ combined the prayers.
