Sunan of Abu Dawood Book 1, Hadith 275

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، وَيَزِيدُ بْنُ خَالِدِ بْنِ يَزِيدَ بْنِ عَبْدِ اللَّهِ بْنِ مَوْهَبٍ، قَالاَ حَدَّثَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّ رَجُلاً، أَخْبَرَهُ عَنْ أُمِّ سَلَمَةَ، أَنَّ امْرَأَةً، كَانَتْ تُهَرَاقُ الدَّمَ ‏.‏ فَذَكَرَ مَعْنَاهُ قَالَ ‏ "‏ فَإِذَا خَلَّفَتْ ذَلِكَ وَحَضَرَتِ الصَّلاَةُ فَلْتَغْتَسِلْ ‏"‏ ‏.‏ بِمَعْنَاهُ ‏.‏

Sulaiman b. Yasar said that a man reported to him from Umm Salamah; There was a woman who had an issue of blood. And he narrated the rest of the tradition to the same effect saying; when the menstruation period is over and the time of prayer arrives, she should take a bath, as mentioned in the previous tradition
