Sahih Muslim Book 7, Hadith Number 2888.

Chapter : Excellence of entry into Mecca from the upper side and exit from it from the lower side, and entering the town from the side other than that from which one gets out.

‘Aisha (Allah be pleased with her) reported that Allah’s Messenger (may peace be upon him) entered Mecca during the year of Victory from Kada i.e. from the upper side. Hisham said: My father entered It from both the Fides, but generally he entered from Kada.
