لِّتُنذِرَ‌ أُمَّ الْقُرَ‌ىٰ (So that you may warn the town that is the mother of all towns) - Umm-ul- Qura (mother of all the towns) means the origin and foundation of all habitations and cities which is Makkah. This title has been given to this city because, to Allah Almighty, it is more distinguished and more excellent than all other cities, habitations and the whole earth. Imam Ahmad has narrated in Musnad, with the authority of Sayyidna ` Adiyy Ibn Hamra' Az-zuhri ؓ that he heard the Messenger of Allah at a market of Makkah when he ﷺ was migrating from the city. He ﷺ was addressing Makkah in the following words:

انک لخیر ارض اللہ و احبّ ارض اللہ اَلَیَّ ولو لا اِنّی اُخرجت منک لما خرجت

"To me, you are better and dearer than the whole of Allah's earth; if I had not been expelled from your vicinity, I would never have left it of my own accord." (At-tirmidhi, An-Nasa'i, Ibn Majah - rated as ` hasan ahib' by Tirmidhi)

وَمَنْ حَوْلَهَا - means the suburbs in the neighborhood of Makkah Mukarramah; it could mean the neighboring Arab countries as well as the whole of the earth from east to west.
