Hadith 7:94
Abu Huraira reported God’s messenger as saying that “There is no might and no power except in God” is a remedy for ninety-nine diseases, the lightest of which is anxiety.
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ دَوَاءٌ مِنْ تِسْعَةٍ وَتِسْعِينَ دَاء أيسرها الْهم»
