Sayyiduna Usama bin Zaid narrated: I asked Tawus during a journey about dhikr and voluntary prayers, while Hasan bin Muslim bin Yanaq was sitting. So Hasan said: Tawus narrated to me from Sayyiduna Ibn Abbas (may Allah be pleased with them), he said: The Messenger of Allah (peace and blessings be upon him) prescribed the obligatory prayer for both residence and travel, and just as prayers are offered before and after it in residence, he said: In the same way, prayers will be offered before and after it during travel.
