[Machine] Regarding this verse {Allah knows what every female carries and what the wombs lose] (Al-Ra'd 8), Ikrimah said, "This refers to the menstrual blood on the umbilical cord. It does not menstruate for a day on the cord unless it increases its purity in its cord."
عَنْ عِكْرِمَةَ فِي هَذِهِ الْآيَةِ {اللَّهُ يَعْلَمُ مَا تَحْمِلُ كُلُّ أُنْثَى وَمَا تَغِيضُ الْأَرْحَامُ وَمَا تَزْدَادُ وَكُلُّ شَيْءٍ عِنْدَهُ بِمِقْدَارٍ} [الرعد 8] قَالَ «ذَلِكَ الْحَيْضُ عَلَى الْحَبَلِ لَا تَحِيضُ يَوْمًا فِي الْحَبَلِ إِلَّا زَادَتْهُ طَاهِرًا فِي حَبَلِهَا»
