صحيح مسلم 110

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

Rapporté par Jabir رضي الله عنه : Un homme a dit un jour au Messager d’Allah ﷺ : « Est-ce que j’entrerai au Paradis si j’accomplis les prières obligatoires, si je jeûne le Ramadan, si je considère comme licite ce qu’Allah a permis et si je m’abstiens de ce qui est interdit, sans rien y ajouter ? » Le Prophète ﷺ répondit : « Oui. » L’homme dit : « Par Allah, je n’y ajouterai rien. »
