Hadith: Whoever dies while not associating anything with Allah will enter Paradise

عَنْ جَابِرٍ، قَالَ: أَتَى النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ رَجُلٌ فَقَالَ: يَا رَسُولَ اللهِ، مَا الْمُوجِبَتَانِ؟ فَقَالَ: «مَنْ مَاتَ لَا يُشْرِكُ بِاللهِ شَيْئًا دَخَلَ الْجَنَّةَ، وَمَنْ مَاتَ يُشْرِكُ بِاللهِ شَيْئًا دَخَلَ النَّارَ»
[صحيح] - [رواه مسلم]

Jābir (may Allah be pleased with him) reported: A man came to the Prophet (may Allah’s peace and blessings be upon him) and said: "O Messenger of Allah, what are the two imperatives? He said: "Whoever dies while not associating anything with Allah will enter Paradise, and whoever dies while associating anything with Allah will enter Hellfire."
Sahih/Authentic. - [Muslim]

Explanation

A man came to the Prophet (may Allah’s peace and blessings be upon him) and asked him about what makes entering Paradise due and what makes entering Hellfire due, and he replied that the thing that makes entering Paradise due for a man is to die while not associating anything with Allah Almighty, and the thing that makes entering Hellfire due for a man is to die while ascribing partners to Allah.
