Sahih Bukhari Volume 5, Book 59, Hadith Number 558.

Narrated By Ibn Abbas : The Prophet hastened in going around the Ka’ba and between the Safa and Marwa in order to show the pagans his strength. Ibn ‘Abbas added, “When the Prophet arrived (at Mecca) in the year of peace (following that of Al-Hudaibiya treaty with the pagans of Mecca), he (ordered his companions) to do Ramal in order to show their strength to the pagans and the pagans were watching (the Muslims) from (the hill of) Quaiqan.
