Sunan Abi Dawud 283
This tradition has also been transmitted by Zuhair through a different chain of narrators, to the same effect. He said:
When the menstruation begins, you should abandon prayer; when the period equal to its length of time passes, you should wash away the blood and pray.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ هِشَامٍ، بِإِسْنَادِ زُهَيْرٍ وَمَعْنَاهُ وَقَالَ ‏
"‏ فَإِذَا أَقْبَلَتِ الْحَيْضَةُ فَاتْرُكِي الصَّلاَةَ فَإِذَا ذَهَبَ قَدْرُهَا فَاغْسِلِي الدَّمَ عَنْكِ وَصَلِّي ‏"‏ ‏.‏
