And to recite the Qur’ān." And whoever is guided is only guided for [the benefit of] himself; and whoever strays - say, "I am only [one] of the warners."
(Say: "O you mankind! If you are in doubt as to my religion, then (know that) I will never worship those whom you worship besides Allah. But I worship Allah Who causes you to die.) (10:104) The fact that the word "Rabb" (Lord) is connected to the word city (in the phrase "the Lord of this city") is a sign of honor and divine care for that city. This is like the Ayah,
رَبَّ هَـٰذِهِ الْبَلْدَةِ (the Lord of this city - 27:91). Majority of the commentators have taken the word o=ff "Baldah" (the city) for Makkah. Allah Ta’ ala is the Lord of all the worlds and the Lord of heavens and earth. Therefore, the particular mention of Makkah here is to show its revered splendor, and its respect and honour in the sight of Allah Ta a1a. Word Haram is derived from Tahrim, which means "to prohibit" and also means "complete respect and veneration", and because of this respect and veneration whatever special religious prohibitions are applicable to Makkah and its surrounding land are also included in it. For instance, whoever takes refuge in Haram is secured. It is not allowed to kill or take revenge from anyone in the Haram. Even hunting of animals and cutting of trees is not permitted in the precincts of Haram. These restrictions are enjoined in the verse وَمَن دَخَلَهُ كَانَ آمِنًا (and whoever enters there is secure - 3:97), while some of them have appeared in the beginning of Surah Ma’ idah. In addition, verse لَا تَقْتُلُوا الصَّيْدَ وَأَنتُمْ حُرُمٌ (do not kill game when, you are in Ihram - 5:95) also includes this subject.
The reference to ‘this town’ (Makkah) here is in relation to the first addressees of the Quran. However, indirectly, this verse reminds all mankind of the eternal reality that there is only one right way and that is to become worshippers of the one God. It is the duty of a preacher to address others, i.e. to give the call of Truth. In this call of the preacher, which has apparently no power behind it, the hearer has to see the might of God. Those who prove their ability to do this, will be of those who will be treated as deserving of the eternal blessing of God.
