عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا الْعَبْدُ أَدَّى حَقَّ اللَّهِ وَحَقَّ مَوَالِيهِ كَانَ لَهُ أَجْرَانِ قَالَ فَحَدَّثْتُهُمَا كَعْبًا قَالَ كَعْبٌ لَيْسَ عَلَيْهِ حِسَابٌ وَلَا عَلَى مُؤْمِنٍ مُزْهِدٍ
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When a slave fulfills the rights of Allah Almighty and the rights of his master, he will have a double reward. The narrator says: When I related this hadith to Sayyiduna Ka'b (may Allah be pleased with him), he said: There is no reckoning for such a slave, nor for a believer with little wealth.
