Al-Adab Al-Mufrad, Book 2, Hadith 1 (In-Book) ⓘ

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."

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.‏
