Sahih Muslim Book - 13, Hadith - 2731

وَحَدَّثَنِيهِ زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ حَدَّثَنَا حُسَيْنٌ الْمُعَلِّمُ عَنْ يَحْيَى بْنِ أَبِى كَثِيرٍ بِهَذَا الإِسْنَادِ وَزَادَ فِيهِ بَعْدَ قَوْلِهِ « مِنْ كُلِّ شَهْرٍ ثَلاَثَةَ أَيَّامٍ » « فَإِنَّ لَكَ بِكُلِّ حَسَنَةٍ عَشْرَ أَمْثَالِهَا فَذَلِكَ الدَّهْرُ كُلُّهُ ». وَقَالَ فِى الْحَدِيثِ قُلْتُ وَمَا صَوْمُ نَبِىِّ اللَّهِ دَاوُدَ قَالَ « نِصْفُ الدَّهْرِ ». وَلَمْ يَذْكُرْ فِى الْحَدِيثِ مِنْ قِرَاءَةِ الْقُرْآنِ شَيْئًا وَلَمْ يَقُلْ « وَإِنَّ لِزَوْرِكَ عَلَيْكَ حَقًّا ». وَلَكِنْ قَالَ « وَإِنَّ لِوَلَدِكَ عَلَيْكَ حَقًّا ».

It was narrated from Yahya bin Abi Kathir with this chain (a Hadith similar to no. 2730), and the words “three days of every month” he added: “for every good deed you will have a tenfold reward, so that is like an entire lifetime.” And he said in the Hadith: “What is the fast of Dawud the Prophet of Allah?” he said: “Half a lifetime.” And he did not mention in the Hadith anything about reciting Qur’an, and he did not say: “Your guests have a right over you,” but he said: “Your child has a right over you.”
