Allah is informing us that He never destroys a township until He has
established evidences for it and its allotted time has ended. When the time for
a nation's destruction has come, He never delays it, and He never moves its
appointed time forward. This was a message and a warning to the people of
Makkah, telling them to give up their Shirk, their stubbornness and disbelief
for which they deserved to be destroyed.
[وَقَالُواْ
يأَيُّهَا الَّذِى نُزِّلَ عَلَيْهِ الذِّكْرُ إِنَّكَ لَمَجْنُونٌ - لَّوْ مَا
تَأْتِينَا بِالْمَلَـئِكَةِ إِن كُنتَ مِنَ الصَّـدِقِينَ - مَا نُنَزِّلُ
الْمَلَـئِكَةَ إِلاَّ بِالحَقِّ وَمَا كَانُواْ إِذًا مُّنظَرِينَ - إِنَّا نَحْنُ
نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَـفِظُونَ ]
(6. And they say: "O you (Muhammad) to whom the Dhikr (the Qur'an) has been
revealed! Verily, you are a madman!) (7. "Why do you not bring angels to us if
you are of the truthful'') (8. We do not send the angels down except with the
truth, and in that case, they (the disbelievers) would have no respite!) (9.
Verily, We, it is We Who revealed the Dhikr (i.e. the Qur'an) and surely We will
guard it (from corruption).)
