What is the guidance on Tawaf-al-Wada` for the Prophet Muhammad's (peace be upon him) followers according to the hadith shared by Ibn `Abbas (saw)?
 Narrated Ibn `Abbas:                     The people were ordered to perform the Tawaf of the Ka`ba (Tawaf-al-Wada`) as the lastly thing, before leaving (Mecca), except the menstruating women who were excused.
