The Messenger of Allah (may Allah’s peace and blessings be upon him) entered Makkah from Kadā', from the upper mountain pass which is in Al-Bat-hā', and exited from the lower mountain pass.

Explanation

The Messenger of Allah (may Allah’s peace and blessings be upon him) performed the Farewell Hajj and stayed overnight at a place named Dhu Tuwa on the fourth night of Dhu al-Hijjah. In the morning, he entered Makkah from its upper mountain pass. It was easier for him to enter from there because he came from Madīnah. When he completed the rituals of Hajj, he exited Makkah and headed towards Madīnah from the lower mountain pass. This road passes though Jarwal. It is possible that he did this intentionally to change his route, so that he may gain more reward for having done more good acts on different paths. This is similar to what he did on his way to ‘Arafah and his return therefrom, and for the Eid prayer, as well as praying the voluntary prayers in a place other than the one where he prayed his obligatory prayers. The purpose of this alteration is for different spots of the earth to testify to his good deeds on the Day when it will relate its news. It is possible that he entered from one place and left from another because both of them were just convenient for whomever would come from Madīnah or leave for it. Allah knows best.
