Abu Ishaq narrated: "I heard 'Amr bin Al-Harith say: 'The Messenger of Allah did not leave behind anything except his white mule, his weapon and some land which he left as a charity.'"
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنِي أَبُو إِسْحَاقَ، قَالَ سَمِعْتُ عَمْرَو بْنَ الْحَارِثِ، يَقُولُ مَا تَرَكَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلاَّ بَغْلَتَهُ الْبَيْضَاءَ وَسِلاَحَهُ وَأَرْضًا تَرَكَهَا صَدَقَةً .
