عَلِيٌّ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) طَهِّرُوا أَوْلَادَكُمْ يَوْمَ السَّابِعِ فَإِنَّهُ أَطْيَبُ وَ أَطْهَرُ وَ أَسْرَعُ لِنَبَاتِ اللَّحْمِ وَ إِنَّ الْأَرْضَ تَنْجَسُ مِنْ بَوْلِ الْأَغْلَفِ أَرْبَعِينَ صَبَاحاً .
2. Ali has narrated from his father from al-Nawfaliy from al-Sakuniy who has said the following: “Abu ‘Abd Allah , has said that the Messenger of Allah. O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘Cleanse (circumcise) your children on the seventh day of their birth; it is more clean and allows the flesh to grow quicker. The land remains unclean for forty days because of the urine of an uncircumcised man.’”
