Abu Bakr and 'Umar gave him the glad tidings that the Messenger of Allah had said: "Whoever would like to recite the Qur'an as fresh as when it was revealed, let him recite it like Ibn Umm 'Abd.'" (Using translation from Ibn Mājah 138)  

قَالَ رَسُولُ اللهِ ﷺ مَنْ أَحَبَّ أَنْ يَقْرَأَ الْقُرْآنَ غَضًّا كَمَا أُنْزِلَ فَلْيَقْرَأْهُ عَلَى قِرَاءَةِ ابْنِ أُمِّ عَبْدٍ  

[Machine] Ishaq ibn al-Mustaliq said, "The Messenger of Allah ﷺ did not leave behind anything except his weapon, a white mule, and a land that he made as charity."  

إِسْحَاقُ بْنُ الْمُصْطَلِقِ يَقُولُ مَا تَرَكَ رَسُولُ اللهِ ﷺ إِلَّا سِلَاحَهُ وَبَغْلَةً بَيْضَاءَ وَأَرْضًا جَعَلَهَا صَدَقَةً
