The piercing (of the hole) in the ear of the boy is from the Sunnah, and his circumcision within seven days is from the Sunnah.

عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ اخْتِنُوا أَوْلَادَكُمْ لِسَبْعَةِ أَيَّامٍ فَإِنَّهُ أَطْهَرُ وَ أَسْرَعُ لِنَبَاتِ اللَّحْمِ وَ إِنَّ الْأَرْضَ لَتَكْرَهُ بَوْلَ الْأَغْلَفِ

Ali Bin Ibrahim, from haroun Bin Muslim, from Mas’ada Bin Sadaqa,

(It has been narrated) from Abu Abdullah^–asws having said: ‘Circumcise your children within seven days, for it purifies and (makes it) easier for the growth of the flesh, and the earth dislikes the urine of the uncircumcised’.

وَ بِهَذَا الْإِسْنَادِ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) إِنَّ ثَقْبَ أُذُنِ الْغُلَامِ مِنَ السُّنَّةِ وَ خِتَانَهُ لِسَبْعَةِ أَيَّامٍ مِنَ السُّنَّةِ

And by this chain, said, ‘Abu Abdullah^-asws said: ‘The piercing (of the hole) in the ear of the boy is from the Sunnah, and his circumcision within seven days is from the Sunnah’.[1]

وَ عَنْهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ ثَقْبُ أُذُنِ الْغُلَامِ مِنَ السُّنَّةِ وَ خِتَانُ الْغُلَامِ مِنَ السُّنَّةِ

And from him, from Ahmad Bin Muhammad Bin Isa, from Muhammad Bin Isa, from Abdullah Bin Sinan,

(It has been narrated) from Abu Abdullah^-asws having said: ‘Piercing the ear of the boy is from the Sunnah, and circumcision of the boy is from the Sunnah’.[2]

عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ الْحُسَيْنِ بْنِ خَالِدٍ قَالَ سَأَلْتُ أَبَا الْحَسَنِ الرِّضَا ( عليه السلام ) عَنِ التَّهْنِئَةِ بِالْوَلَدِ مَتَى فَقَالَ إِنَّهُ قَالَ لَمَّا وُلِدَ الْحَسَنُ بْنُ عَلِيٍّ هَبَطَ جَبْرَئِيلُ بِالتَّهْنِئَةِ عَلَى النَّبِيِّ ( صلى الله عليه وآله ) فِي الْيَوْمِ السَّابِعِ وَ أَمَرَهُ أَنْ يُسَمِّيَهُ وَ يُكَنِّيَهُ وَ يَحْلِقَ رَأْسَهُ وَ يَعُقَّ عَنْهُ وَ يَثْقُبَ أُذُنَهُ وَ كَذَلِكَ كَانَ حِينَ وُلِدَ الْحُسَيْنُ ( عليه السلام ) أَتَاهُ فِي الْيَوْمِ السَّابِعِ فَأَمَرَهُ بِمِثْلِ ذَلِكَ

Ali Bin Ibrahim, from his father, from Al Husayn Bin Khalid who said,

‘I asked Abu Al-Hassan Al-Reza^-asws about the congratulations with the birth, when (should it be done)?’ So he said, ‘He^-asws said: ‘Upon the ‘Nazool’ (appearance) from Heavens) of Al-Hassan Bin Ali^-asws, Jibraeel^-as descended with the congratulations upon the Prophet^-saww during the seventh day, and instructed him^-saww that he^-saww should name him^-asws, and teknonym him^-asws, and shave off his^-asws head, and perform Aqeeqa for him^-asws, and pierce hole in his^‑asws ear’. And similar to that was when Al-Husayn^-asws‘s Nazool. He (Jibraeel^-as) came to him^-saww during the seventh day. So he^-as instructed him^-asws with similar to that’.

قَالَ وَ كَانَ لَهُمَا ذُؤَابَتَانِ فِي الْقَرْنِ الْأَيْسَرِ وَ كَانَ الثَّقْبُ فِي الْأُذُنِ الْيُمْنَى فِي شَحْمَةِ الْأُذُنِ وَ فِي الْيُسْرَى فِي أَعْلَى الْأُذُنِ فَالْقُرْطُ فِي الْيُمْنَى وَ الشَّنْفُ فِي الْيُسْرَى

He^-asws said: ‘And for both of them^-asws were to forelocks in the top right, and the hole in the right ear was in the lobe of the ear, and in the left, it was in the upper part of the ear. So the ear-ring (الْقُرْطُ) was in the right, and the ear-ring (الشَّنْفُ) in the left’.

وَ قَدْ رُوِيَ أَنَّ النَّبِيَّ ( صلى الله عليه وآله ) تَرَكَ لَهُمَا ذُؤَابَتَيْنِ فِي وَسَطِ الرَّأْسِ وَ هُوَ أَصَحُّ مِنَ الْقَرْنِ

And it has been reported that the Prophet^-saww left for both of them^-asws, two forelocks in the middle of the head, and it is more correct than the top’.[3]
