Nafi' reported on the authority of Ibn Umar (Allah be pleased with them) that Messenger of Allah ﷺ walked swiftly from stone to stone in three circuits and walked (normally) in four. (Using translation from Muslim 1262a)
«رَمَلَ رَسُولُ اللَّهِ ﷺ مِنَ الْحَجَرِ إِلَى الْحَجَرِ ثَلَاثًا وَمَشَى أَرْبَعًا»
