Full Sharh — Al-Adab Al-Mufrad 910
حَدَّثَنَا مَكِّيُّ بْنُ إِبْرَاهِيمَ، قَالَ: أَخْبَرَنَا ابْنُ جُرَيْجٍ، عَنْ عَطَاءٍ، عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا رَأَى مَخِيلَةً دَخَلَ وَخَرَجَ، وَأَقْبَلَ وَأَدْبَرَ، وَتَغَيَّرَ وَجْهُهُ، فَإِذَا مَطَرَتِ السَّمَاءُ سُرِّيَ، فَعَرَّفَتْهُ عَائِشَةُ ذَلِكَ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم: وَمَا أَدْرِي لَعَلَّهُ كَمَا قَالَ اللَّهُ عَزَّ وَجَلَّ: {فَلَمَّا رَأَوْهُ عَارِضًا مُسْتَقْبِلَ أَوْدِيَتِهِمْ}.
English Translation
'A'isha said, "When the Prophet, may Allah bless him and grant him peace, saw a cloud in the sky, he would get up and down and walk to and fro, and his face would change colour. When it rained, that would leave him." When A'isha commented on that, the Prophet, may Allah bless him and grant him peace, said, "I do not know. Perhaps it will be as Allah Almighty says:: 'When they saw it as a storm cloud advancing on their valleys...' (46:24)"
