[Machine] Narrated by the Prophet ﷺ, he said: "Whoever prays twelve voluntary Rak'ahs in a day, other than the obligatory prayers, Allah will build a house for him in Paradise." Abu Abdur-Rahman said, "This Hadith is incorrect according to me, and Muhammad bin Sulaiman is weak. Fulayh bin Sulaiman contradicts him and narrates it from Suhail, who narrates it from Abu Ishaq."
عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ صَلَّى فِي يَوْمٍ ثِنْتَيْ عَشْرَةَ رَكْعَةً سِوَى الْفَرِيضَةِ بَنَى اللهُ لَهُ بَيْتًا فِي الْجَنَّةِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا الْحَدِيثُ عِنْدِي خَطَأٌ وَمُحَمَّدُ بْنُ سُلَيْمَانَ ضَعِيفٌ وَقَدْ خَالَفَهُ فُلَيْحُ بْنُ سُلَيْمَانَ فَرَوَاهُ عَنْ سُهَيْلِ عَنْ أَبِي إِسْحَاقَ
