Musnad Ahmad Hadith 2624

The Messenger of Allah (ﷺ) and his companions came (to Makkah) when the fever of Yathrib had weakened them, and the mushrikeen said: There have come to you people who have been weakened by fever. Allah informed the Prophet (ﷺ) of that, so he instructed his Companions to trot (raml), as the mushrikeen were sitting near the Hijr, watching them. They trotted (raml), and walked between the two corners, and the mushrikeen said: Are these the ones who you said have been weakened by the fever? These are stronger than such and such. Ibn ‘Abbas (رضي الله عنه) said: Nothing prevented him from telling them to trot in all the circuits except kindness towards them.
