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 .
Aisha narrated that she made a will to `Abdullah bin Zubair, "Do not bury me with them (the Prophet (ﷺ) 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)."
