حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ‏:‏ حَدَّثَنَا ضَمْضَمُ بْنُ عَمْرٍو الْحَنَفِيُّ، قَالَ‏:‏ حَدَّثَنَا كُلَيْبُ بْنُ مَنْفَعَةَ قَالَ‏:‏ قَالَ جَدِّي‏:‏ يَا رَسُولَ اللهِ، مَنْ أَبَرُّ‏؟‏ قَالَ‏:‏ أُمَّكَ وَأَبَاكَ، وَأُخْتَكَ وَأَخَاكَ، وَمَوْلاَكَ الَّذِي يَلِي ذَاكَ، حَقٌّ وَاجِبٌ، وَرَحِمٌ مَوْصُولَةٌ‏.‏

Kulayb ibn Manfa'a reported that his grandfather asked, "Messenger of Allah, towards whom should I be dutiful?" He replied, "Your mother, your father, your sister and your brother. Then your mawla (client) has the next right against you and then your relatives who are connected."
