The Destruction of Towns, which are not destroyed until Evidence is established against Them

Referring to the people of Makkah, Allah says:

وَكَمْ أَهْلَكْنَا مِن قَرْيَةٍ بَطِرَتْ مَعِيشَتَهَا

حَتَّىٰ يَبْعَثَ فِي أُمِّهَا رَ‌سُولًا (Unless he sends to their central place a messenger -28:59). Popular meaning of the word 'Umm is mother, and since mother is the very basis of human creation, hence the word 'Umm (اُمَّ ) is also used extensively for origin, base, and foundation. The pronoun ha (translated above as 'their' ) refers back to the towns, and 'mother of the towns' means the central town. The meaning of the verse is that Allah Ta` ala does not destroy a people unless He had sent His message through His messengers in their main cities. When the invitation to truth had reached, and yet people did not accept it, only then the torment is sent on those cities.

This verse has pointed out that Allah's messengers and prophets are generally sent in big cities, and not in smaller towns, because such towns are normally under the influence of big cities, both for their economic and educational needs. If something is known in a big city, it becomes known automatically in the smaller towns around it. Hence, when a prophet is sent in a big city and he starts his call to the truth, the message is spread out in the surrounding towns in no time. This way Allah Ta` ala's message reaches to all and sundry, and if they reject the message of truth, the torment is sent to all of them.
