٢- أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيْهِما السَّلام) قَالَ إِذَا زَوَّجَ الرَّجُلُ ابْنَةَ ابْنِهِ فَهُوَ جَائِزٌ عَلَى ابْنِهِ وَلابْنِهِ أَيْضاً أَنْ يُزَوِّجَهَا فَقُلْتُ فَإِنْ هَوِيَ أَبُوهَا رَجُلا وَجَدُّهَا رَجُلا فَقَالَ الْجَدُّ أَوْلَى بِنِكَاحِهَا.
2. Ahmad ibn Muhammad has narrated from Ali ibn al-Hakam from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “One of the two Imam, (abu Ja’far or abu ‘Abd Allah) , has said, ‘If a man gives in marriage his granddaughter to a man, it is binding upon his son and his son also can give her in marriage.’ I then asked, ‘What happens if her father likes one man and her grandfather prefers another man?’ He (the Imam) said, ‘Grandfather has greater priority.’”
