Hadith: O Abu Sa‘īd, whoever is pleased with Allah as a Lord, with Islam as a religion, and with Muhammad as a messenger, Paradise is guaranteed for him

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضيَ اللهُ عنهُ أَنَّ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ:
«يَا أَبَا سَعِيدٍ، مَنْ رَضِيَ بِاللهِ رَبًّا، وَبِالْإِسْلَامِ دِينًا، وَبِمُحَمَّدٍ نَبِيًّا، وَجَبَتْ لَهُ الْجَنَّةُ»، فَعَجِبَ لَهَا أَبُو سَعِيدٍ، فَقَالَ: أَعِدْهَا عَلَيَّ يَا رَسُولَ اللهِ، فَفَعَلَ، ثُمَّ قَالَ: «وَأُخْرَى يُرْفَعُ بِهَا الْعَبْدُ مِائَةَ دَرَجَةٍ فِي الْجَنَّةِ، مَا بَيْنَ كُلِّ دَرَجَتَيْنِ كَمَا بَيْنَ السَّمَاءِ وَالْأَرْضِ»، قَالَ: وَمَا هِيَ يَا رَسُولَ اللهِ؟ قَالَ: «الْجِهَادُ فِي سَبِيلِ اللهِ، الْجِهَادُ فِي سَبِيلِ اللهِ».
[صحيح] - [رواه مسلم] - [صحيح مسلم: 1884]

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said:
"O Abu Sa‘īd, whoever is pleased with Allah as a Lord, with Islam as a religion, and with Muhammad as a messenger, Paradise is guaranteed for him." Abu Sa‘īd was full of wonder at that, so he said: O Messenger of Allah, repeat that to me. He did so and then said: "There is something else by means of which the slave is raised a hundred degrees in Paradise; the distance between each two degrees is like that between the heavens and the earth." He said: O Messenger of Allah, what is it? He said: "Jihad for the sake of Allah, Jihad for the sake of Allah."
[Authentic hadith] - [Narrated by Muslim] - [Sahih Muslim - 1884]

Explanation

The Prophet (may Allah's peace and blessings be upon him) informed Abu Sa‘īd al-Khudri (may Allah be pleased with him) that whoever believes in Allah, accepts Him as a Lord, God, Owner, Master, and Commander, embraces Islam as a religion, submitting and surrendering to all of its commands and prohibitions, and believes in Muhammad (may Allah's peace and blessings be upon him) as a prophet with everything he was sent with and conveyed, Paradise will be guaranteed for him. Abu Sa‘īd (may Allah be pleased with him) was amazed and asked: Repeat it to me, O Messenger of Allah, and he did. Then the Prophet (may Allah's peace and blessings be upon him) added: And I have another quality by which Allah raises a slave by one hundred degrees in Paradise; the distance between every two degrees is like that between the heavens and the earth. Abu Sa‘īd asked: What is it, O Messenger of Allah? He replied: Jihad for the sake of Allah, Jihad for the sake of Allah.
