Sunan Ibn Majah, Book 37, Hadith 4308 (In-Book) ⓘ
It was narrated from Abu Hurairah that the Messenger of Allah said: “A wise word is the lost property of the believer, so wherever he finds it, he has more right to it.”
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ الْوَهَّابِ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، عَنْ إِبْرَاهِيمَ بْنِ الْفَضْلِ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " الْكَلِمَةُ الْحِكْمَةُ ضَالَّةُ الْمُؤْمِنِ حَيْثُمَا وَجَدَهَا فَهُوَ أَحَقُّ بِهَا " .
