The stubborn Response of the Disbelievers

Allah tells us that if people were to be punished before proof was established against them, they would use the excuse that no Messenger came to them, but when the truth did come to them through Muhammad ﷺ, in their stubbornness, disbelief, ignorance and misguided thinking, they said:

لَوْلا أُوتِىَ مِثْلَ مَآ أُوتِىَ مُوسَى

وَلَقَدْ وَصَّلْنَا لَهُمُ الْقَوْلَ لَعَلَّهُمْ يَتَذَكَّرُ‌ونَ (And We have conveyed (Our) words to them one after the other, so that they may take to advice. - 28:51). The word وَصَّلْنَا (wassalna) is derived from وتَصِیل (Tausil), which literally means to strengthen the rope by adding more strings to its strands. Here it means that Allah Ta` ala has maintained the continuity of guidance. Certain advisory subjects are repeated in the Qur'an in order to make them more effective.
