Sunan Ibn Majah, Book 23, Hadith 2831 (In-Book) ⓘ
‘Umar bin Khattab said: “There are three things, if the Messenger of Allah had clarified them, that would have been dearer to me than the world and everything in it: a person who leaves behind no heir, usury, and the caliphate.”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا عَمْرُو بْنُ مُرَّةَ، عَنْ مُرَّةَ بْنِ شَرَاحِيلَ، قَالَ قَالَ عُمَرُ بْنُ الْخَطَّابِ ثَلاَثٌ لأَنْ يَكُونَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَيَّنَهُنَّ أَحَبُّ إِلَىَّ مِنَ الدُّنْيَا وَمَا فِيهَا الْكَلاَلَةُ وَالرِّبَا وَالْخِلاَفَةُ .
