Sahih Bukhari Volume 4, Book 59, Hadith 3320

حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي أُوَيْسٍ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ نَزَلَ نَبِيٌّ مِنَ الأَنْبِيَاءِ تَحْتَ شَجَرَةٍ فَلَدَغَتْهُ نَمْلَةٌ، فَأَمَرَ بِجَهَازِهِ فَأُخْرِجَ مِنْ تَحْتِهَا، ثُمَّ أَمَرَ بِبَيْتِهَا فَأُحْرِقَ بِالنَّارِ، فَأَوْحَى اللَّهُ إِلَيْهِ فَهَلاَّ نَمْلَةً وَاحِدَةً ‏"‏‏

Narrated By Abu Huraira : Allah's Apostle said, "Once while a prophet amongst the prophets was taking a rest underneath a tree, an ant bit him. He, therefore, ordered that his luggage be taken away from underneath that tree and then ordered that the dwelling place of the ants should be set on fire. Allah sent him a revelation: "Wouldn't it have been sufficient to burn a single ant?
