Hadith 223

Narrated 'Abdullah bin Abi Aufa (RA): A man came to the Prophet (ﷺ) and said, "I cannot memorize anything from the Qur'an, so teach me something which can be a substitute for me." He said, "Say Subhan Allah (Allah is Free of Imperfections) walhamdu lillah (and praise is to Allah), wa la ilaha illa-Allah (and there is nothing worthy of worship except Allah), wallahu akbar (and Allah is the Most Great), wa la hawla wa la quwwata illa billah al-'Ali al-'Adheem (and there is no might and no strength but in Allah, the Most High, the Supreme)" [Reported by Ahmad, Abu Dawud and An-Nasa'i; and Ibn Hibban, ad-Daraqutni and Al-Hakim graded it Sahih (authentic)].
