Did you not see those who exhibit ingratitude in exchange for Allah’s favours and make their people alight into the home of loss, hell, they will enter it and it is an evil place (and time for) staying. (Al Quran, Surah Ibrahim, Chapter 14: Verses 28-29)
Summarized Commentary:
Some people, are ungrateful to Allah (SWT), these will be punished in hell.
Narrated Ata:
When Ibn `Abbas heard: “Have you not seen those who have changed the favor of Allah into disbelief?” (14.28) he said, “Those were the disbelieving pagans of Mecca.”
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ عَطَاءٍ، سَمِعَ ابْنَ عَبَّاسٍ، {أَلَمْ تَرَ إِلَى الَّذِينَ بَدَّلُوا نِعْمَةَ اللَّهِ كُفْرًا} قَالَ هُمْ كُفَّارُ أَهْلِ مَكَّةَ.
