question #3 Sahih Muslim 1277e, Book 15, Hadith 289 : What is the significance of performing Hajj or Umra in relation to the Signs of Allah as mentioned in the verse?

” Verily al-Safa’ and al-Marwa are among the Signs of Allah” ; so he who performs Hajj or Umra, for him there is no harm if he should circumambulate between them, and he who does good spontaneously-surely Allah is Bountiful in rewarding and Knowing.
