It was narrated that Anas said: “A man asked the Messenger of Allah ﷺ : ‘Messenger of Allah ﷺ , how many prayers has Allah enjoined upon His slaves?’ He said: ‘Allah has enjoined upon His slaves (five) prayers.’ He said: ‘Messenger of Allah ﷺ , is there anything before them or after them?’ He said: ‘Allah has enjoined upon His slaves (five) prayers.’ The man swore that he would not do anything more or less than that. The Messenger of Allah ﷺ said: ‘If he is speaking the truth he will most certainly enter Paradise.” (Sahih)
