Abu Nazrah says: Sayyiduna Imran bin Husain (may Allah be pleased with him) was passing by, so we sat down and a young man from the group went to him and asked him about the prayer of the Messenger of Allah (peace and blessings be upon him) during journeys of battle, Hajj, and Umrah. He came and stood among us and said: This young man has asked me a question, and I want all of you to hear its answer. The matter is that I performed jihad with the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) prayed two rak‘ahs until he returned to Madinah. I also performed Hajj with him (peace and blessings be upon him), and (on that journey too) he (peace and blessings be upon him) performed only two rak‘ahs until he returned to Madinah. Then I was present with him (peace and blessings be upon him) at the conquest of Makkah, and he (peace and blessings be upon him) stayed there for eighteen days and prayed only two rak‘ahs, but he (peace and blessings be upon him) used to say to the people of the city: You should pray four rak‘ahs, because we are travelers. Then I performed three Umrahs with him (peace and blessings be upon him), and he (peace and blessings be upon him) continued to pray only two rak‘ahs. After that, I performed several Hajj with Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them), and both of them used to pray only two rak‘ahs until they returned to Madinah.
