Narrated 'Aisha:

That she asked the Prophet , 'Have you encountered a day harder than the day of the battle) of Uhud?" The Prophet replied, "Your tribes have troubled me a lot, and the worse trouble was the trouble on the day of 'Aqaba when I presented myself to Ibn 'Abd-Yalail bin 'Abd-Kulal and he did not respond to my demand. So I departed, overwhelmed with excessive sorrow, and proceeded on, and could not relax till I found myself at Qarnath-Tha-alib where I lifted my head towards the sky to see a cloud shading me unexpectedly. I looked up and saw Gabriel in it. He called me saying, 'Allah has heard your people's saying to you, and what they have replied back to you, Allah has sent the Angel of the Mountains to you so that you may order him to do whatever you wish to these people.' The Angel of the Mountains called and greeted me, and then said, "O Muhammad! Order what you wish. If you like, I will let Al-Akh-Shabain (i.e. two mountains) fall on them." The Prophet ﷺ said, "No but I hope that Allah will let them beget children who will worship Allah Alone, and will worship None besides Him."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، قَالَ حَدَّثَنِي عُرْوَةُ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ زَوْجَ النَّبِيِّ ﷺ حَدَّثَتْهُ أَنَّهَا قَالَتْ لِلنَّبِيِّ ﷺ هَلْ أَتَى عَلَيْكَ يَوْمٌ كَانَ أَشَدَّ مِنْ يَوْمِ أُحُدٍ قَالَ
" لَقَدْ لَقِيتُ مِنْ قَوْمِكِ مَا لَقِيتُ، وَكَانَ أَشَدُّ مَا لَقِيتُ مِنْهُمْ يَوْمَ الْعَقَبَةِ، إِذْ عَرَضْتُ نَفْسِي عَلَى ابْنِ عَبْدِ يَالِيلَ بْنِ عَبْدِ كُلاَلٍ، فَلَمْ يُجِبْنِي إِلَى مَا أَرَدْتُ، فَانْطَلَقْتُ وَأَنَا مَهْمُومٌ عَلَى وَجْهِي، فَلَمْ أَسْتَفِقْ إِلاَّ وَأَنَا بِقَرْنِ الثَّعَالِبِ، فَرَفَعْتُ رَأْسِي، فَإِذَا أَنَا بِسَحَابَةٍ قَدْ أَظَلَّتْنِي، فَنَظَرْتُ فَإِذَا فِيهَا جِبْرِيلُ فَنَادَانِي فَقَالَ إِنَّ اللَّهَ قَدْ سَمِعَ قَوْلَ قَوْمِكَ لَكَ وَمَا رَدُّوا عَلَيْكَ، وَقَدْ بَعَثَ إِلَيْكَ مَلَكَ الْجِبَالِ لِتَأْمُرَهُ بِمَا شِئْتَ فِيهِمْ، فَنَادَانِي مَلَكُ الْجِبَالِ، فَسَلَّمَ عَلَىَّ ثُمَّ قَالَ يَا مُحَمَّدُ، فَقَالَ ذَلِكَ فِيمَا شِئْتَ، إِنْ شِئْتَ أَنْ أُطْبِقَ عَلَيْهِمِ الأَخْشَبَيْنِ، فَقَالَ النَّبِيُّ ﷺ بَلْ أَرْجُو أَنْ يُخْرِجَ اللَّهُ مِنْ أَصْلاَبِهِمْ مَنْ يَعْبُدُ اللَّهَ وَحْدَهُ لاَ يُشْرِكُ بِهِ شَيْئًا ".
