اِنَّ الصَّفَا وَ الْمَرْوَةَ مِنْ شَعَآىٕرِ اللّٰهِۚ-فَمَنْ حَجَّ الْبَیْتَ اَوِ اعْتَمَرَ فَلَا جُنَاحَ عَلَیْهِ اَنْ یَّطَّوَّفَ بِهِمَاؕ-وَ مَنْ تَطَوَّعَ خَیْرًاۙ-فَاِنَّ اللّٰهَ شَاكِرٌ عَلِیْمٌ(۱۵۸)

Translation from Kanz-ul-Iman: Undoubtedly Safa and Marwah (two hills near the Holy Ka’bah) are amongst the signs of Allah ; so whosoever performs Hajj or ‘Umrah of this Sacred House, there is no sin upon him (for) walking between both of them, and whosoever does some good (i.e. optional worship) on his own accord, then indeed Allah  is Most Appreciative, All-Knowing.

Meeqat

7. Those coming from outside the Meeqat cannot enter Makkah without an Ihram.

Definition of Meeqat

Meeqat is that place where Afaqi (the person who lives outside the limits of Meeqat) is unable to enter Haram unless he is in Ihram, even if he comes for the purpose of business or anything else. Even the residents of Makkah, going out of Meeqat (e.g. Madinah or Taif), are not permitted to re-enter Makkah without Ihram (Rafeeq-ul-Haramayn, pp. 63)

8. Muslims from around the world visit Makkah to perform Hajj.

9. Whosoever enters this sacred city will attain peace. Therefore, it is stated in Para 1, Surah Al-Baqarah, Verse 126:

وَ اِذْ قَالَ اِبْرٰهٖمُ رَبِّ اجْعَلْ هٰذَا بَلَدًا اٰمِنًا

Translation from Kanz-ul-Iman: And (recall) when Ibrahim requested, ‘O my Lord, make this city (Makkah) a peaceful one.
