في صحيح البخاري ( 97 ) عن أبي هريرة رضي الله عنه أَنَّهُ قَالَ قِيلَ يَا رَسُولَ اللَّهِ مَنْ أَسْعَدُ النَّاسِ بِشَفَاعَتِكَ يَوْمَ الْقِيَامَةِ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَقَدْ ظَنَنْتُ يَا أَبَا هُرَيْرَةَ أَنْ لا يَسْأَلُنِي عَنْ هَذَا الْحَدِيثِ أَحَدٌ أَوَّلُ مِنْكَ لِمَا رَأَيْتُ مِنْ حِرْصِكَ عَلَى الْحَدِيثِ أَسْعَدُ النَّاسِ بِشَفَاعَتِي يَوْمَ الْقِيَامَةِ مَنْ قَالَ لا إِلَهَ إِلا اللَّهُ خَالِصًا مِنْ قَلْبِهِ أَوْ نَفْسِه "ِ
In Sahih al-Bukhari (97) on the authority of Abu Hurairah, may God be pleased with him, it was said, O Messenger of God, who will be the happiest of people through your intercession on the Day of Resurrection? The Messenger of God said: I thought, O Abu Hurai, that he does not ask me about this hadith, one best more than you, for I see from your keen on the hadith, the best who's take my intercession on the day of the resurrection, who's said no God except God pure from his heart or his soul.
WE benefit from the noble Hadith
1 - Just as in the world there are happy people and there are people who claim (the happiest people) in the afterlife it is even greater, the afterlife is greater because there is no return, no work, no attempt to please the Lord blessed and exalted again, only as a result of work.
2- The Prophet - peace be upon him - has many intercessions on the Day of Resurrection, including (who's the happiest one with His intercession, who said there is no god but Allah pure from his heart, and we understood it, what is it in himself? Perhaps because at the end of time there are hundreds or thousands of earthly religions, some of which are under arms and their adherents are not allowed to leave this religion for any reason, if someone says it one day between him and himself or is revered in his heart, he is one of the happiest people with the intercession of the Messenger of Allah on the Day of Judgment.
