عَنِ الْحَارِثِ بْنِ مُسْلِمِ بْنِ الْحَارِثِ التَّمِيمِيِّ عَنْ أَبِيهِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَتَبَ لَهُ كِتَابًا بِالْوَصَاةِ لَهُ إِلَى مَنْ بَعْدَهُ مِنْ وُلَاةِ الْأَمْرِ وَخَتَمَ عَلَيْهِ
Harith bin Muslim bin Harith Tamimi narrates from his father that the Noble Prophet (peace and blessings be upon him and his family) wrote a document for him, in which he bequeathed in their favor by mentioning the names of the caliphs to come after him, and sealed it.
