It is narrated on the authority of Jabir that Nu'man b. Qaufal came to the Prophet (ﷺ) and said:Would I enter Paradise if I say the obligatory prayers and deny myself that which is forbidden and treat that as lawful what has been made permissible (by the Shari'ah)? The Prophet (ﷺ) replied in the affirmative

A similar hadith is narrated on Jabir's authority in which the following words are added:I will do nothing more

It is narrated on the authority of Jabir that a man once said to the Messenger of Allah (ﷺ):Shall I enter Paradise in case I say the obligatory prayers, observe the (fasts) of Ramadan and treat that as lawful which has been made permissible (by the Shari'ah) and deny myself that what is forbidden, and make no addition to it? He (the Holy Prophet) replied in the affirmative. He (the inquirer) said: By Allah, I would add nothing to it
