أَخْبَرَنَا أَبُو نُعَيْمٍ ، حَدَّثَنَا الْحَسَنُ ، عَنْ مُغِيرَةَ ، عَنْ الشَّعْبِيِّ ، قَالَ :" إِذَا فَرَّطَتْ ثُمَّ حَاضَتْ، قَضَتْ "

Abu Nu`aym told us, Al-Hasan told us, on the authority of Mughirah, on the authority of Al-Shabi, he said: “If she missed her period and then had her period, she should make up for it.”
