Sahih al-Bukhari, Hadith 4951 ⓘ
Narrated Jundub Al-Bajali: A lady said, "O Allah's Messenger! I see that your friend has delayed. (in conveying Qur'an) to you." So there was revealed: 'Your Lord (O Muhammad) has neither forsaken you, not hated you.' (93.1-3)
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، غُنْدَرٌ حَدَّثَنَا شُعْبَةُ، عَنِ الأَسْوَدِ بْنِ قَيْسٍ، قَالَ سَمِعْتُ جُنْدَبًا الْبَجَلِيَّ، قَالَتِ امْرَأَةٌ يَا رَسُولَ اللَّهِ مَا أُرَى صَاحِبَكَ إِلاَّ أَبْطَأَكَ. فَنَزَلَتْ {مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى}
