٤- مُحَمَّدُ بْنُ يَحْيَى عَنْ بَعْضِ أَصْحَابِنَا عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ إِسْحَاقَ بْنِ جَرِيرٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ قُلْتُ لَهُ الرَّجُلُ يَفْجُرُ بِالْمَرْأَةِ ثُمَّ يَبْدُو لَهُ فِي تَزْوِيجِهَا هَلْ يَحِلُّ لَهُ ذَلِكَ قَالَ نَعَمْ إِذَا هُوَ اجْتَنَبَهَا حَتَّى تَنْقَضِيَ عِدَّتُهَا بِاسْتِبْرَاءِ رَحِمِهَا مِنْ مَاءِ الْفُجُورِ فَلَهُ أَنْ يَتَزَوَّجَهَا وَإِنَّمَا يَجُوزُ لَهُ أَنْ يَتَزَوَّجَهَا بَعْدَ أَنْ يَقِفَ عَلَى تَوْبَتِهَا. 
4. Muhammad ibn Yahya has narrated from certain persons of our people from ‘Uthman ibn ‘Isa from Ishaq ibn Jarir who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a man who commits an indecent act (goes to bed with her out of wedlock) with a woman and then decides to marry her; if it is lawful for him. He (the Imam) said, ‘Yes, it is lawful if he waits until her waiting period is complete to cleans her womb from indecent activities; then he can marry her and it is only when he ascertains that she has repented.’”
