2870. Narrated Abū Ishāq: Mūsā bin 'Uqba said, Nāfi' said: Ibn 'Umar رضي الله عنه said, "Allāh's Messenger ﷺ arranged a horse race amongst the horses that had been made lean, letting them start from Al-Ḥafyā' and their limit (distance of running) was up to Thanīyat Al-Wadā'. I asked Mūsā, 'What was the distance between the two places?' Mūsā replied, 'Six or seven miles. He arranged a race of the horses which had not been made lean sending them from Thanīyat-Al-Wadā', and their limit was up to the mosque of Banī Zuraīq.' I asked, 'What was the distance between those two places?' He replied 'One mile or so.' Ibn 'Umar was amongst those who participated in that horse race."
