Sunan Ibn Majah
Sunan Ibn Majah 54
حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ الْهَمْدَانِيُّ، حَدَّثَنِي رِشْدِينُ بْنُ سَعْدٍ، وَجَعْفَرُ بْنُ عَوْنٍ، عَنِ ابْنِ أَنْعُمٍ، - هُوَ الإِفْرِيقِيُّ - عَنْ عَبْدِ الرَّحْمَنِ بْنِ رَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " الْعِلْمُ ثَلاَثَةٌ فَمَا وَرَاءَ ذَلِكَ فَهُوَ فَضْلٌ آيَةٌ مُحْكَمَةٌ أَوْ سُنَّةٌ قَائِمَةٌ أَوْ فَرِيضَةٌ عَادِلَةٌ " .
Muhammad ibn al-Ala al-Hamdani narrated to us: Rushdin ibn Sad and Jafar ibn Awn narrated to me, from Ibn Anam—namely al-Ifriqi—from Abd al-Rahman ibn Rafi, from Abdullah ibn Amr, who said: The Messenger of Allah (peace and blessings be upon him) said: Knowledge consists of three things; whatever is beyond them is extra: a clear verse, an established Sunnah, or a just obligation.
Translation notes
The Arabic lists a clear verse, an established Sunnah, and a just obligation. The English witness interprets the final phrase as rulings by which inheritance is divided fairly, but inheritance is not specified in the Arabic, so that gloss is omitted. The chain itself identifies Ibn Anam as al-Ifriqi.
