What did the Prophet Muhammad (saw) instruct a woman who had recently finished her menstrual period to do in order to purify herself?
 'A'isha reported:                      A woman asked the Apostle of Allah (may peace be upon him) how he should wash herself after the menstrual period. He (the Holy Prophet) said: Take a cotton with musk and purity yourself, and the rest of the hadith was narrated like that of Sufyan.
