"I asked 'Abdullah bin Abu Awfa about killing locusts and he said: I went on six campaigns with the Messenger of Allah hand we ate locusts."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ سُفْيَانَ، - وَهُوَ ابْنُ عُيَيْنَةَ - عَنْ أَبِي يَعْفُورٍ، قَالَ سَأَلْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى عَنْ قَتْلِ الْجَرَادِ، فَقَالَ غَزَوْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم سِتَّ غَزَوَاتٍ نَأْكُلُ الْجَرَادَ ‏.‏
