Hadith 22:175
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (may peace he upon him) as saying:
One should not take a span of land without having legitimate right to it, otherwise Allah would make him wear (around his neck) seven earths on the Day of Resurrection.
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَأْخُذُ أَحَدٌ شِبْرًا مِنَ الأَرْضِ بِغَيْرِ حَقِّهِ إِلاَّ طَوَّقَهُ اللَّهُ إِلَى سَبْعِ أَرَضِينَ يَوْمَ الْقِيَامَةِ "
