Chapter 54 | Marriage without Witness
1- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنْ زُرَارَةَ بْنِ أَعْيَنَ قَالَ سُئِلَ أَبُو عَبْدِ اللهِ عَنِ الرَّجُلِ يَتَزَوَّجُ الْمَرْأَةَ بِغَيْرِ شُهُودٍ فَقَالَ لا بَأْسَ بِتَزْوِيجِ الْبَتَّةِ فِيمَا بَيْنَهُ وَبَيْنَ اللهِ إِنَّمَا جُعِلَ الشُّهُودُ فِي تَزْوِيجِ الْبَتَّةِ مِنْ أَجْلِ الْوَلَدِ لَوْ لا ذَلِكَ لَمْ يَكُنْ بِهِ بَأْسٌ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah from Zurarah ibn ‘A‘yan who has said the following: “Once abu ‘ Abd Allah , was asked about the case of a man who married a woman without witness. He (the Imam) said, ‘It is not unlawful at all between him and Allah. Witness in marriage is for the sake of children, if that is not the concern then it is not unlawful.’”
