Arabic (Original)
حَدَّثَنَا رَوْحٌ حَدَّثَنَا هَمَّامٌ عَنْ أَنَسِ بْنِ سِيرِينَ عَنْ عَبْدِ الْمَلِكِ بْنِ قَتَادَةَ بْنِ مِلْحَانَ الْقَيْسِيِّ عَنْ أَبِيهِ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَأْمُرُنَا أَنْ نَصُومَ اللَّيَالِي الْبِيضَ ثَلَاثَ عَشْرَةَ وَأَرْبَعَ عَشْرَةَ وَخَمْسَ عَشْرَةَ وَقَالَ هُنَّ كَهَيْئَةِ الدَّهْرِ.
English Translation
Rawh told us: Hammam told us, from Anas ibn Sirin, from Abd al-Malik ibn Qatadah ibn Milhan al-Qaysi, from his father, who said: The Messenger of Allah (peace and blessings be upon him) used to command us to fast the white nights: the thirteenth, fourteenth, and fifteenth, and he said: "They are like [fasting] a lifetime."
