The Idolators deserved Allah's Torment after Their Atrocities

Allah states that the idolators deserved the torment, but He did not torment them in honor of the Prophet residing among them. After Allah allowed the Prophet to migrate away from them, He sent His torment upon them on the day of Badr. During that battle, the chief pagans were killed, or captured. Allah also directed them to seek forgiveness for the sins, Shirk and wickedness they indulged in. If it was not for the fact that there were some weak Muslims living among the Makkan pagans, those Muslims who invoked Allah for His forgiveness, Allah would have sent down to them the torment that could never be averted. Allah did not do that on account of the weak, ill-treated, and oppressed believers living among them, as He reiterated about the day at Al-Hudaybiyyah,

هُمُ الَّذِينَ كَفَرُواْ وَصَدُّوكُمْ عَنِ الْمَسْجِدِ الْحَرَامِ وَالْهَدْىَ مَعْكُوفاً أَن يَبْلُغَ مَحِلَّهُ وَلَوْلاَ رِجَالٌ مُّؤْمِنُونَ وَنِسَآءٌ مُّؤْمِنَـتٌ لَّمْ تَعْلَمُوهُمْ أَن تَطَئُوهُمْ فَتُصِيبَكمْ مِّنْهُمْ مَّعَرَّةٌ بِغَيْرِ عِلْمٍ لِّيُدْخِلَ اللَّهُ فِى رَحْمَتِهِ مَن يَشَآءُ لَوْ تَزَيَّلُواْ لَعَذَّبْنَا الَّذِينَ كَفَرُواْ مِنْهُمْ عَذَاباً أَلِيماً

Commentary

It was said in previous verses that the disbelievers of Makkah were though deserving, because of their disbelief and denial, of heavenly punishment coming down upon them, but the presence of the Holy Prophet ﷺ in Makkah was a prohibitive factor against the coming of a mass punishment on them. Then, after his migration to Madinah, such punishment would still not come upon them because of the weaker ones among Muslims who, while living in Makkah, kept seeking forgiveness from Allah.
