حَدَّثَنَا إِسْمَاعِيلُ أَنْبَأَنَا هِشَامٌ قَالَ كَتَبَ إِلَيَّ يَحْيَى بْنُ أَبِي كَثِيرٍ يُحَدِّثُ عَنْ عِكْرِمَةَ أَنَّ عُمَرَ كَانَ يَقُولُ فِي الْحَرَامِ يَمِينٌ يُكَفِّرُهَا قَالَ هِشَامٌ وَكَتَبَ إِلَيَّ يَحْيَى يُحَدِّثُ عَنْ يَعْلَى بْنِ حَكِيمٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ أَنَّ ابْنَ عَبَّاسٍ كَانَ يَقُولُ فِي الْحَرَامِ يَمِينٌ يُكَفِّرُهَا فَقَالَ ابْنُ عَبَّاسٍ لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ
مسند امام احمد بن حنبل · Hadith 1976
It was narrated from 'Ikrimah that 'Umar used to say concerning declaring one's wife to be haram : It is an oath for which expiation must be offered. Hisham said: Yahya wrote to me, narrating from Ya'la bin Hakeem, from Sa'eed bin Jubair, that Ibn 'Abbas used to say concerning declaring one's wife to be haram: It is an oath for which expiation must be offered. And Ibn 'Abbas said: "Indeed in the Messenger of Allah (Muhammad (PBUH)) you have a good example to follow for him" [al-Ahzab 33:21],
