Allah's Apostle you have a good example

Bukhari :: Book 2 :: Volume 26 :: Hadith 704
Narrated Nafi':

Ibn 'Umar intended to perform Hajj in the year when Al-Hajjaj attacked Ibn Az-Zubair. Somebody said to Ibn 'Umar, "There is a danger of an impending war between them." Ibn 'Umar said, "Verily, in Allah's Apostle you have a good example. (And if it happened as you say) then I would do the same as Allah's Apostle had done. I make you witness that I have decided to perform 'Umra." Then he set out and when he reached Al-Baida', he said, "The ceremonies of both Hajj and 'Umra are similar. I make you witness that I have made Hajj compulsory for me along with 'Umra." He drove (to Mecca) a Hadi which he had bought from (a place called) Qudaid and did not do more than that. He did not slaughter the Hadi or finish his Ihram, or shave or cut short his hair till the day of slaughtering the sacrifices (10th Dhul-Hijja). Then he slaughtered his Hadi and shaved his head and considered the first Tawaf (of Safa and Marwa) as sufficient for Hajj and 'Umra. Ibn 'Umar said, "Allah's Apostle did the same."

Narrated Nafi':

Ibn 'Umar said, "When Allah's Apostle performed the first Tawaf he did Ramal in the first three rounds and then walked in the remaining four rounds (of Tawaf of the Ka'ba), where as in performing Tawaf between Safa and Marwa he used to run in the midst of the rain-water passage," I asked Nafi', "Did 'Abdullah (bin 'Umar) use to walk steadily on reaching the Yemenite Corner?" He replied, "No, unless people were crowded at the Corner; otherwise he would not leave it without touching it."
