مُحَمَّدٌ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ زِيَادِ بْنِ أَبِي الْحَلَّالِ عَنْ أَبِي عَبْدِ اللَّهِ (عليه السلام) قَالَ قَالَ مُوسَى (عليه السلام) يَا رَبِّ مِنْ أَيْنَ الدَّاءُ قَالَ مِنِّي قَالَ فَالشِّفَاءُ قَالَ مِنِّي قَالَ فَمَا يَصْنَعُ عِبَادُكَ بِالْمُعَالِجِ قَالَ يُطَيِّبُ بِأَنْفُسِهِمْ فَيَوْمَئِذٍ سُمِّيَ الْمُعَالِجُ الطَّبِيبَ.

Where does illness come from?’ He (azwj) Said: “From Me (azwj)”. He said: ‘And the cure?’ He (azwj) Said: “From Me (azwj)”. He said: ‘So what do Your servants do with the healer?’ He (azwj) Said: “They soothe themselves by him”. These days the healer is called the Doctor’.
