Arabic (Original)
حَدَّثَنَا هَارُونُ بْنُ مَعْرُوفٍ قَالَ أَخْبَرَنِي ابْنُ وَهْبٍ أَخْبَرَنِي حَيْوَةُ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي عَبْدِ اللَّهِ مَوْلَى شَدَّادِ بْنِ الْهَادِ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ سَمِعَ رَجُلًا يَنْشُدُ فِي الْمَسْجِدِ ضَالَّةً فَلْيَقُلْ لَا أَدَّاهَا اللَّهُ عَلَيْكَ فَإِنَّ الْمَسَاجِدَ لَمْ تُبْنَ لِذَلِكَ.
English Translation
Harun ibn Ma'ruf narrated to us, he said: Ibn Wahb informed me, Haywah informed me, from Muhammad ibn Abd al-Rahman, from Abu Abdullah, the freed slave of Shaddad ibn al-Had, that he heard Abu Hurayrah saying: I heard the Messenger of Allah (peace and blessings of Allah be upon him) saying: "Whoever hears a man announcing a lost item in the mosque, let him say: 'May Allah not return it to you,' for the mosques were not built for that."
