سنن أبي داود#3472Hasanحَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عُثْمَانُ بْنُ الْحَكَمِ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ قَالَ لاَ جَائِحَةَ فِيمَا أُصِيبَ دُونَ ثُلُثِ رَأْسِ الْمَالِ - قَالَ يَحْيَى - وَذَلِكَ فِي سُنَّةِ الْمُسْلِمِينَ .
Yahya b. Sa'id said:Blight is not effective when less than one-third of goods are damaged. Yayha said: That has been the established practice of Muslims
