أَخْبَرَنَا مُحَمَّدُ بْنُ يُوسُفَ ، حَدَّثَنَا سُفْيَانُ ، عَنْ لَيْثٍ ، عَنْ عَطَاءٍ فِي الْكَبِيرَةِ تَرَى الدَّمَ، قَالَ :" لَا نَرَاهُ حَيْضًا "

Muhammad ibn Yusuf told us, Sufyan told us, on the authority of Layth, on the authority of Ata’ who sees blood in a woman’s uterus. He said: “We do not see it as menstruation.”
