عَن سعيد بْنِ زَيْدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ أَخَذَ شِبْرًا مِنَ الْأَرْضِ ظُلْمًا فَإِنَّهُ يُطَوَّقُهُ يَوْمَ الْقِيَامَةِ مِنْ سبع أَرضين»

Sa’id b. Zaid reported God’s Messenger as saying, “If anyone takes a span of land unjustly, its extent taken from seven earths will be tied round his neck on the day of resurrection.” (Bukhari and Muslim.)
