حَدَّثَنَا
بَهْزٌ ، حَدَّثَنَا
شُعْبَةُ ، حَدَّثَنِي
أَنَسُ بْنُ سِيرِينَ ، عَنْ
عَبْدِ الْمَلِكِ رَجُلٍ مِنْ بَنِي قَيْسِ بْنِ ثَعْلَبَةَ ، عَنْ
أَبِيهِ , أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ
يَأْمُرُهُمْ بِصِيَامِ أَيَّامِ الْبِيضِ , وَيَقُولُ : " هُنَّ صِيَامُ الشَّهْرِ " , أَوْ قَالَ : " الدَّهْرِ " .
It is narrated from Hazrat Qatadah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) commanded us to fast on the white days, that is, the 13th, 14th, and 15th of the lunar month, which in reward are equal to fasting the entire month.
