It was narrated from Ibn ‘Abbas (رضي الله عنه) that

Quraish said: Muhammad and his companions have been weakened by the fever of Yathrib. When the Messenger of Allah (ﷺ) came in the year in which he did ‘Umrah, he said to his companions: "Trot around the House so that the mushrikeen may see your strength. When they trotted, Quraish said: It did not make them weak.
