Hadith on Paradise: Believers do not enter Paradise until absolved from sin

Abu Sa’id al-Khudri reported: The Messenger of Allah, peace and blessings be upon him, said, “When the believers are saved from Hellfire, they will be held at a bridge between Paradise and Hell. They will requite each other for wrongs done in the world, until they are purified and absolved and they will be called to enter Paradise. By the One in whose hand is the soul of Muhammad, one of you will recognize his place in Paradise better than he did his home in the world.”

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا خَلَصَ الْمُؤْمِنُونَ مِنْ النَّارِ حُبِسُوا بِقَنْطَرَةٍ بَيْنَ الْجَنَّةِ وَالنَّارِ فَيَتَقَاصُّونَ مَظَالِمَ كَانَتْ بَيْنَهُمْ فِي الدُّنْيَا حَتَّى إِذَا نُقُّوا وَهُذِّبُوا أُذِنَ لَهُمْ بِدُخُولِ الْجَنَّةِ فَوَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَأَحَدُهُمْ بِمَسْكَنِهِ فِي الْجَنَّةِ أَدَلُّ بِمَنْزِلِهِ كَانَ فِي الدُّنْيَا
