Muwatta Malik 1308

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، أَنَّ جَدَّهُ، مُحَمَّدَ بْنَ عَمْرِو بْنِ حَزْمٍ بَاعَ ثَمَرَ حَائِطٍ لَهُ يُقَالُ لَهُ الأَفْرَاقُ بِأَرْبَعَةِ آلاَفِ دِرْهَمٍ وَاسْتَثْنَى مِنْهُ بِثَمَانِمِائَةِ دِرْهَمٍ تَمْرًا ‏.‏

Yahya related to me from Malik from Abdullah ibn Abi Bakr that his grandfather, Muhammad ibn Amr ibn Hazm sold the fruit of an orchard of his called al-Afraq, for 4,000 dirhams, and he kept aside 800 dirhams' worth of dry dates
