Muhammad said: 'Allah the Most High has ninety-nine names. He who retains them in his memory will enter Paradise'
He also said: 'No-one is afflicted by distress or anxiety then invokes Allah with this supplication, but Allah will take away his distress and grant him happiness instead'
وَ لِلَّهِ الأسْمآءُ الْحُسْنَى فَادْعُوهُ بِهَا
"Allah's are the Most Beautiful Names, so call Him with them" (7:180)
هُوَ اللَّهُ الَّذِي لا إلَهَ إلَّا هُوَ He is Allah, there is none worthy of worship except for Him
