"I passed by the Prophet (saas) and he said to me: 'O Hazim, say often: "La hawla wa la quwwata illa billah (there is no power and no strength except with Allah)," for it is one of the treasures of Paradise.'" (Using translation from Ibn Mājah 3826)
أَنَّ النَّبِيَّ ﷺ قَالَ أَكْثِرُوا مِنْ قَوْلِ لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ فَإِنَّهَا كَنْزٌ مِنْ كُنُوزِ الْجَنَّةِ
