باب اسْتِحْبَابِ دُخُولِ مَكَّةَ مِنَ الثَّنِيَّةِ الْعُلْيَا وَالْخُرُوجِ مِنْهَا مِنَ الثَّنِيَّةِ السُّفْلَى وَدُخُولِ بَلْدَةٍ مِنْ طَرِيقٍ غَيْرِ الَّتِي خَرَجَ مِنْهَا
Sahih Muslim 1258 b

A'isha (Allah be pleased with her) reported that Allah's Messenger (ﷺ) 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.

وَحَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم دَخَلَ عَامَ الْفَتْحِ مِنْ كَدَاءٍ مِنْ أَعْلَى مَكَّةَ ‏.‏ قَالَ هِشَامٌ فَكَانَ أَبِي يَدْخُلُ مِنْهُمَا كِلَيْهِمَا وَكَانَ أَبِي أَكْثَرَ مَا يَدْخُلُ مِنْ كَدَاءٍ ‏.‏
