Hadith #2

2- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ سَأَلْتُ أَبَا إِبْرَاهِيمَ (عَلَيْهِ السَّلام) عَنِ الرَّجُلِ يَكُونُ لَهُ أَرْبَعُ نِسْوَةٍ فَيُطَلِّقُ إِحْدَاهُنَّ أَيَتَزَوَّجُ مَكَانَهَا أُخْرَى قَالَ لا حَتَّى تَنْقَضِيَ عِدَّتُهَا.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Ali ibn abu Hamzah who has said the following: “This is concerning my question before abu Ibrahim, ‘Alayhi al-Salam, about the case of a man who has four wives; if he can divorce one and marry in her place another one. He (the Imam) said, ‘No, he cannot do so until her waiting period is complete.’”
