question #3 Sahih Muslim 1211r, Book 15, Hadith 136 : What is the significance of performing Umrah from Tan’im after the menstrual period ends?

Messenger of Allah. the people return (from Mecca) having done two worships (both Hajj and Umra), but I am coming back with one (only). whereupon he said: You should wait and when the period of menses is over, you should go to Tan’im and put on lhram and then meet us at such and such time (and I think he said tomorrow) ; and (the reward of this Umra) is for you equal to your hardship or your spending.
