وَ سَأَلَ سَعْدُ بْنُ سَعْدٍ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلصَّبِيِّ هَلْ يُرْضَعُ أَكْثَرَ مِنْ سَنَتَيْنِ فَقَالَ "عَامَيْنِ" قُلْتُ فَإِنْ زَادَ عَلَى سَنَتَيْنِ هَلْ عَلَى أَبَوَيْهِ مِنْ ذَلِكَ شَيْءٌ قَالَ "لاَ".
Sa'd ibn Sa'd asked Imam Ali ibn Musa Ar-Ridha (a.s) about whether a child can be breastfed for more than two years. Imam (a.s) replied: "Two years." I asked: "If it exceeds two years, is there any obligation upon the parents because of that?" Imam (a.s) said: "No."
