3875 - وَ رَوَى عُمَرُ بْنُ حَنْظَلَةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : فِي رَجُلٍ بَاعَ أَرْضاً عَلَى أَنَّ فِيهَا عَشَرَةَ أَجْرِبَةٍ فَاشْتَرَى اَلْمُشْتَرِي ذَلِكَ مِنْهُ بِحُدُودِهِ وَ نَقَدَ اَلثَّمَنَ وَ أَوْقَعَ صَفْقَةَ اَلْبَيْعِ وَ اِفْتَرَقَا فَلَمَّا مَسَحَ اَلْأَرْضَ إِذَا هِيَ خَمْسَةُ أَجْرِبَةٍ قَالَ "إِنْ شَاءَ اِسْتَرْجَعَ فَضْلَ مَالِهِ وَ أَخَذَ اَلْأَرْضَ وَ إِنْ شَاءَ رَدَّ اَلْبَيْعَ وَ أَخَذَ مَالَهُ كُلَّهُ إِلاَّ أَنْ تَكُونَ إِلَى حَدِّ تِلْكَ اَلْأَرْضِ لَهُ أَيْضاً أَرَضُونَ فَيُوَفِّيَهُ وَ يَكُونُ اَلْبَيْعُ لاَزِماً لَهُ وَ اَلْوَفَاءُ لَهُ بِتَمَامِ اَلْمَبِيعِ فَإِنْ لَمْ يَكُنْ لَهُ فِي ذَلِكَ اَلْمَكَانِ غَيْرُ اَلَّذِي بَاعَ فَإِنْ شَاءَ اَلْمُشْتَرِي أَخَذَ اَلْأَرْضَ وَ اِسْتَرْجَعَ فَضْلَ مَالِهِ وَ إِنْ شَاءَ رَدَّ وَ أَخَذَ اَلْمَالَ كُلَّهُ".
Hadith.3875 - Umar bin Hanzalah narrated from Abu Abdillah 
regarding a man who sold a piece of land, claiming it contained ten jaribs, and the buyer purchased it with its boundaries specified, paid the price, concluded the sale, and they separated.
However, when the land was measured, it turned out to be only five jaribs.
Imam said: "If the buyer wishes, he may reclaim the excess amount of his payment and keep the land, or if he wishes, he may cancel the sale and take back all his money, unless the seller owns additional land adjacent to the specified boundaries and fulfills the remainder of the agreed quantity. In that case, the sale remains valid, and the seller must complete the agreed quantity. However, if the seller does not own any additional land in that area beyond what he sold, then the buyer has the option to keep the land and reclaim the excess amount of his payment, or cancel the sale entirely and recover all his money."
