Majma al-Zawaid — Hadith 2958

Thumamah bin Shurahbil narrated: I came to Sayyiduna Abdullah bin Umar and asked: "What is the prayer of the traveller?" He said: "Two rak'ahs each, except for the Maghrib prayer, which is three." I said: "What is your view if we are at Dhu al-Majaz?" He said: "What is Dhu al-Majaz?" I replied: "It is a place where we gather and buy and sell (that is, a fair is held there), and we stay there for twenty days or fifteen days." Sayyiduna Abdullah bin Umar said: "O people, I was in Azerbaijan" (the narrator said: I think he said: "for four months, or perhaps two months"), "and I saw them offering two rak'ahs each, and I saw with my own eyes the Prophet (peace and blessings be upon him) offering two rak'ahs." Then he recited this verse: "Indeed, in the Messenger of Allah there is an excellent example for you." (Allamah al-Haythami says:) I say: The hadiths narrated from Sayyiduna Abdullah bin Umar in the Sahih and other books are reported without this wording.
Imam Ahmad recorded it, and its narrators are thiqat (trustworthy).
