٥- عَلِيٌّ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ رَجُلٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ قُلْتُ الْجَارِيَةُ ابْنَةُ كَمْ لا تُسْتَصْبَى ابْنَةُ سِتٍّ أَوْ سَبْعٍ فَقَالَ لا ابْنَةُ تِسْعٍ لا تُسْتَصْبَى وَأَجْمَعُوا كُلُّهُمْ عَلَى أَنَّ ابْنَةَ تِسْعٍ لا تُسْتَصْبَى إِلا أَنْ يَكُونَ فِي عَقْلِهَا ضَعْفٌ وَإِلا فَهِيَ إِذَا بَلَغَتْ تِسْعاً فَقَدْ بَلَغَتْ. 
5. Ali has narrated from his father from Ibn Abi ‘Umayr from a man who has said the following: “I once asked abu ‘Abd Allah , ‘When is a girl not considered a child? Is it a girl who is six or seven years old?’ He (the Imam) said, ‘No, a nine-year-old girl is not considered a child and all of them are unanimous that a girl who is nine years old is not considered a child unless there is weakness in her reason, otherwise, when she becomes nine years old she becomes mature.’”
