مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ خَلِيلِ بْنِ عَمْرٍو الْيَشْكُرِيِّ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ كَانَ أَمِيرُ الْمُؤْمِنِينَ ( عليه السلام ) يَقُولُ إِذَا كَانَ الْغُلَامُ مُلْتَاثَ الْأُدْرَةِ صَغِيرَ الذَّكَرِ سَاكِنَ النَّظَرِ فَهُوَ مِمَّنْ يُرْجَى خَيْرُهُ وَ يُؤْمَنُ شَرُّهُقَالَ وَ إِذَا كَانَ الْغُلَامُ شَدِيدَ الْأُدْرَةِ كَبِيرَ الذَّكَرِ حَادَّ النَّظَرِ فَهُوَ مِمَّنْ لَا يُرْجَى خَيْرُهُ وَ يُؤْمَنُ شَرُّهُ .

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad and Ali ibn Ibrahim has narrated from his father from all from ibn Mahbub from Khalil ibn ‘Amr al-Yashkuriy from Jamil ibn Darraj who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that ’Amir al-Mu’minin has said, ’If a boy’s scrotum is relaxed, his penis is small, his eyes are relaxed; then there is hope for goodness to come from him, as well as hope in safety from his evil. On the other hand if a boy whose scrotum is hard, his penis is large and has piercing eyes, he then is one in whose goodness there is no hope nor safety from his evil.’”
