Hadith 1:310
Hasan (Al-Albani)
'Ikrimah reported Hamnah daughter of Jahsh as saying that her husband would have intercourse with her during the period she had a flow of blood.
حَدَّثَنَا أَحْمَدُ بْنُ أَبِي سُرَيْجٍ الرَّازِيُّ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ الْجَهْمِ، حَدَّثَنَا عَمْرُو بْنُ أَبِي قَيْسٍ، عَنْ عَاصِمٍ، عَنْ عِكْرِمَةَ، عَنْ حَمْنَةَ بِنْتِ جَحْشٍ، أَنَّهَا كَانَتْ مُسْتَحَاضَةً وَكَانَ زَوْجُهَا يُجَامِعُهَا
