Ibn Abbas (RA) narrated: “The Messenger of Allah (ﷺ) traveled on a journey and he prayed two Rak’ah for nineteen days.” Ibn Abbas (RA) said: “So when we would stay somewhere for nineteen (days) we would pray two Rak’ah , and if we stayed longer than that we would complete the Salat.”
(Jami` at-Tirmidhi 549, Book 6, Hadith 6)
