Sahih Muslim 160 c
This hadith has been reported from 'A'isha by another chain of transmitters and the words are:
He (the Holy Prophet) came to Khadija an his heart was trembling. The rest of the hadith has been narrated like one transmitted by Yunus and Ma'mar, but the first part is not mentioned, i. e. the first thing with which was started the revelation to the Prophet was the true vision. And these words like those transmitted by Yunus are mentioned thus: By Allah, Allah would never humiliate you. And there is also a mention of the words of Khadija: O son of my uncle! Listen to the son of your brother.
وَحَدَّثَنِي عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ، قَالَ حَدَّثَنِي أَبِي، عَنْ جَدِّي، قَالَ حَدَّثَنِي عُقَيْلُ بْنُ خَالِدٍ، قَالَ ابْنُ شِهَابٍ سَمِعْتُ عُرْوَةَ بْنَ الزُّبَيْرِ، يَقُولُ قَالَتْ عَائِشَةُ زَوْجُ النَّبِيِّ صلى الله عليه وسلم فَرَجَعَ إِلَى خَدِيجَةَ يَرْجُفُ فُؤَادُهُ وَاقْتَصَّ الْحَدِيثَ بِمِثْلِ حَدِيثِ يُونُسَ وَمَعْمَرٍ وَلَمْ يَذْكُرْ أَوَّلَ حَدِيثِهِمَا مِنْ قَوْلِهِ أَوَّلُ مَا بُدِئَ بِهِ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنَ الْوَحْىِ الرُّؤْيَا الصَّادِقَةُ ‏.‏ وَتَابَعَ يُونُسَ عَلَى قَوْلِهِ فَوَاللَّهِ لاَ يُخْزِيكَ اللَّهُ أَبَدًا ‏.‏ وَذَكَرَ قَوْلَ خَدِيجَةَ أَىِ ابْنَ عَمِّ اسْمَعْ مِنِ ابْنِ أَخِيكَ ‏.‏
