'Abdullah said, "The person who has had something stolen from him continues to be suspicious until he is worse than the thief."
حَدَّثَنَا يُوسُفُ بْنُ يَعْقُوبَ، قَالَ: حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ أَخُو عُبَيْدٍ الْقُرَشِيِّ، قَالَ: حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللهِ قَالَ: مَا يَزَالُ الْمَسْرُوقُ مِنْهُ يَتَظَنَّى حَتَّى يَصِيرَ أَعْظَمَ مِنَ السَّارِقِ.
