أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ ابْنِ جُرَيْجٍ، عَنْ عَطَاءٍ فِي الْحَامِلِ تَرَى الدَّمَ وَهِيَ تَطْلُقُ، قَالَ: "تَصْنَعُ مَا تَصْنَعُ الْمُسْتَحَاضَةُ".
It is narrated from Ata (may Allah have mercy on him) regarding a pregnant woman, that if she experiences bleeding at the time of labor pains, then she (the pregnant woman) will do what a woman experiencing istihada (irregular bleeding) does.
