Jami` at-Tirmidhi, Book 48, Hadith 196 (In-Book) ⓘ
Ali narrated, saying: “Whenever the Prophet would visit an ill person, he would said:‘[O Allah,] make the harm go away, Lord of mankind, and heal him, You are the Healer, there is no healing except your healing, a healing that does not leave any sickness ([Allāhumma] adh-hibil-ba’sa rabban-nās, washfi antash-shāfi, lā shifā’a illā shifā’uka shifā’an lā yughādiru saqama).’”
حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْحَارِثِ، عَنْ عَلِيٍّ، رضى الله عنه قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا عَادَ مَرِيضًا قَالَ " اللَّهُمَّ أَذْهِبِ الْبَأْسَ رَبَّ النَّاسِ وَاشْفِ فَأَنْتَ الشَّافِي لاَ شِفَاءَ إِلاَّ شِفَاؤُكَ شِفَاءً لاَ يُغَادِرُ سَقَمًا " . قَالَ هَذَا حَدِيثٌ حَسَنٌ .
