question #2 Sahih al-Bukhari 1769, Book 25, Hadith 245 : What significance does the location of Dhi-Tuwa hold in the journey to and from Makkah?

Whenver Ibn ‘Umar (ra) approached (Makkah) he used to pass the night at Dhi-Tuwa till dawn, and then he would enter Makkah. On his return, he used to pass by Dhi-Tuwa and pass the night there till dawn, and he used to say that the Prophet (ﷺ) used to do the same.
