On the authority of Abu Abdullah Jabir bin Abdullah al-Ansaree (may Allah be pleased with him) that:

A man questioned the Messenger of Allah ﷺ and said, “Do you think that if I perform the obligatory prayers, fast in Ramadhan, treat as lawful that which is halal, and treat as forbidden that which is haram, and do not increase upon that [in voluntary good deeds], then I shall enter Paradise?” He ﷺ replied, “Yes.”

[Muslim]

عَنْ أَبِي عَبْدِ اللَّهِ جَابِرِ بْنِ عَبْدِ اللَّهِ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُمَا: "أَنَّ رَجُلًا سَأَلَ رَسُولَ اللَّهِ ﷺ فَقَالَ: أَرَأَيْت إذَا صَلَّيْت الْمَكْتُوبَاتِ، وَصُمْت رَمَضَانَ، وَأَحْلَلْت الْحَلَالَ، وَحَرَّمْت الْحَرَامَ، وَلَمْ أَزِدْ عَلَى ذَلِكَ شَيْئًا؛ أَأَدْخُلُ الْجَنَّةَ؟ قَالَ: نَعَمْ". [رَوَاهُ مُسْلِمٌ].
