Sahih al-Bukhari, Volume 2, Book 23, Hadith 474 (USC-MSA) ⓘ

Narrated `Urwa: When the wall fell on them (i.e. graves) during the caliphate of Al-Walid bin `Abdul Malik, the people started repairing it, and a foot appeared to them. The people got scared and thought that it was the foot of the Prophet. No one could be found who could tell them about it till I (`Urwa) said to them, "By Allah, this is not the foot of the Prophet but it is the foot of `Umar."

حَدَّثَنَا فَرْوَةُ، حَدَّثَنَا عَلِيٌّ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، لَمَّا سَقَطَ عَلَيْهِمُ الْحَائِطُ فِي زَمَانِ الْوَلِيدِ بْنِ عَبْدِ الْمَلِكِ أَخَذُوا فِي بِنَائِهِ، فَبَدَتْ لَهُمْ قَدَمٌ فَفَزِعُوا، وَظَنُّوا أَنَّهَا قَدَمُ النَّبِيِّ صلى الله عليه وسلم فَمَا وَجَدُوا أَحَدًا يَعْلَمُ ذَلِكَ حَتَّى قَالَ لَهُمْ عُرْوَةُ لاَ وَاللَّهِ مَا هِيَ قَدَمُ النَّبِيِّ صلى الله عليه وسلم مَا هِيَ إِلاَّ قَدَمُ عُمَرَ ـ رضى الله عنه ـ‏.‏

Aisha narrated that she made a will to `Abdullah bin Zubair, "Do not bury me with them (the Prophet and his two companions) but bury me with my companions (wives of the Prophet (p.b.u.h) ) in Al-Baqi as I would not like to be looked upon as better than I really am (by being buried near the Prophet)."

وَعَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّهَا أَوْصَتْ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ ـ رضى الله عنهما ـ لاَ تَدْفِنِّي مَعَهُمْ وَادْفِنِّي مَعَ صَوَاحِبِي بِالْبَقِيعِ، لاَ أُزَكَّى بِهِ أَبَدًا‏.‏
