Sahih (Sahih Muslim)
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 " .
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
