Hadith 1822
1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ وَعَبْدِ الرَّحْمَنِ بْنِ الْحَجَّاجِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ الْكَسِيرُ وَالْمَبْطُونُ يُرْمَى عَنْهُمَا قَالَ وَالصِّبْيَانُ يُرْمَى عَنْهُمْ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar and ‘ Abd al-Rahman ibn al-Hajjaj who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘It is permissible to throw pebbles on behalf of one who has a broken part or has stomach illness and so also is the rule about children.’”
