Sahih Muslim Book - 4, Hadith - 939

حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ حَدَّثَنِي أَبِي عَنْ جَدِّي حَدَّثَنِي عُقَيْلُ بْنُ خَالِدٍ قَالَ قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَتْ لَقَدْ رَاجَعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي ذَلِكَ وَمَا حَمَلَنِي عَلَى كَثْرَةِ مُرَاجَعَتِهِ إِلَّا أَنَّهُ لَمْ يَقَعْ فِي قَلْبِي أَنْ يُحِبَّ النَّاسُ بَعْدَهُ رَجُلًا قَامَ مَقَامَهُ أَبَدًا وَإِلَّا أَنِّي كُنْتُ أَرَى أَنَّهُ لَنْ يَقُومَ مَقَامَهُ أَحَدٌ إِلَّا تَشَاءَمَ النَّاسُ بِهِ فَأَرَدْتُ أَنْ يَعْدِلَ ذَلِكَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ أَبِي بَكْرٍ

It was narrated that 'Aishah, the wife of the Prophet (s.a.w), said: "I tried to discourage the Messenger of Allah (s.a.w) from doing that, and the only thing that made me object so much was the fact that it never occurred to my heart that the people could ever love a man who would stand in his place after he was gone. I thought that whoever stood in his place would be regarded in a superstitious manner by the people, and I wanted the Messenger of Allah (s.a.w) to spare Abu Bakr such a thing."
