Amr ibn Awf reported: The Messenger of Allah, peace and blessings be upon him, said, “By Allah, it is not poverty I fear for you, but rather I fear you will be given the wealth of the world just as it was given to those before you and you will compete for it just as they competed for it and it will destroy you just as it destroyed them.”

عَنْ عَمْرِو بْنِ عَوْفٍ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَاللَّهِ لَا الْفَقْرَ أَخْشَى عَلَيْكُمْ وَلَكِنْ أَخَشَى عَلَيْكُمْ أَنْ تُبْسَطَ عَلَيْكُمْ الدُّنْيَا كَمَا بُسِطَتْ عَلَى مَنْ كَانَ قَبْلَكُمْ فَتَنَافَسُوهَا كَمَا تَنَافَسُوهَا وَتُهْلِكَكُمْ كَمَا أَهْلَكَتْهُمْ
