This tradition has been transmitted through the chain of narrators like that of al-Laith to the same effect. It says; She should abandon prayer considering that period (she used to menstruate). When the time of prayer approaches, she should take a bath, tie a cloth over her private parts and offer prayer.

حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا صَخْرُ بْنُ جُوَيْرِيَةَ، عَنْ نَافِعٍ، بِإِسْنَادِ اللَّيْثِ وَبِمَعْنَاهُ قَالَ ‏

‏ فَلْتَتْرُكِ الصَّلاَةَ قَدْرَ ذَلِكَ ثُمَّ إِذَا حَضَرَتِ الصَّلاَةُ فَلْتَغْتِسِلْ وَلْتَسْتَثْفِرْ بِثَوْبٍ ثُمَّ تُصَلِّي ‏
