It was narrated that Ibn 'Abbas (رضي الله عنه) said:

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 the fever of Yathrib and it has had a bad impact on them. The mushrikeen sat beside the Hijr, and Allah informed the Prophet (ﷺ) of what they had said, so the Messenger of Allah (ﷺ) instructed them (his Companions) to trot (raml) in the first three circuits, to show the mushrikeen how strong they were. So they trotted (raml) in the first three circuits, and he told them to walk between the two corners where the mushrikeen could not see them. Ibn 'Abbas (ﷺ) said: Nothing prevented him from telling them to trot in all the circuits except kindness towards them. And the mushrikeen said: Are these the ones who you said have been weakened by the fever? These are stronger than such and such.
