اتَّقُوا الظُّلْمَ فَإِنَّ الظُّلْمَ ظُلُمَاتٌ يَوْمَ الْقِيَامَةِ وَاتَّقُوا الشُّحَّ فَإِنَّ الشُّحَّ أَهْلَكَ مَنْ كَانَ قَبْلَكُمْ حَمَلَهُمْ عَلَى أَنْ سَفَكُوا دِمَاءَهُمْ وَاسْتَحَلُّوا مَحَارِمَهُمْ

Beware of committing oppression, for oppression will be darkness on the Day of Resurrection. Beware of greed, for greed ruined those before you. It caused them to shed their blood and to make lawful what was unlawful to them.

Beware of committing injustice, for injustice will be darkness on the Day of Resurrection. Beware of obscenity, for Allah does not love obscenity and immorality. Beware of greed, for it tempted those before you and caused them to make lawful what is unlawful, to shed blood and sever their family ties.

إِيَّاكُمْ وَالشُّحَّ فَإِنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِالشُّحِّ أَمَرَهُمْ بِالْبُخْلِ فَبَخِلُوا وَأَمَرَهُمْ بِالْقَطِيعَةِ فَقَطَعُوا وَأَمَرَهُمْ بِالْفُجُورِ فَفَجَرُوا

Beware of greed, for it was only greed that destroyed those before you. It commanded them to be miserly and they did so. It commanded them to sever their family ties and they did so. It commanded them to behave wickedly and they did so.

Ibn Umar reported: The Messenger of Allah, peace and blessings be upon him, said:

ثَلَاثٌ مُهْلِكَاتٌ وَثَلَاثٌ مُنَجِّيَاتٌ وَثَلَاثٌ كَفَّارَاتٌ وَثَلَاثٌ دَرَجَاتٌ فَأَمَّا الْمُهْلِكَاتُ فَشُحٌّ مُطَاعٌ وَهَوًى مُتَّبَعٌ وَإِعْجَابُ الْمَرْءِ بِنَفْسِهِ وَأَمَّا الْمُنَجِّيَاتُ فَالْعَدْلُ فِي الْغَضَبِ وَالرِّضَى وَالْقَصْدُ فِي الْفَقْرِ وَالْغِنَى وَخَشْيَةُ اللَّهِ فِي السِّرِّ وَالْعَلَانِيَةِ وَأَمَّا الْكَفَّارَاتُ فَانْتِظَارُ الصَّلَاةِ بَعْدَ الصَّلَاةِ وَإِسْبَاغُ الْوُضُوءِ فِي السَّبَرَاتِ وَنَقْلُ الْأَقْدَامِ إِلَى الْجَمَاعَاتِ وَأَمَّا الدَّرَجَاتُ فَإِطْعَامُ الطَّعَامِ وَإِفْشَاءُ السَّلَامِ وَصَلَاةٌ بِاللَّيْلِ وَالنَّاسُ نِيَامٌ

Three deeds are destructive vices, three are salvific virtues, three are expiations, and three are a rise in ranks. As for destructive vices, they are greed that is obeyed, whims that are followed, and man being impressed with himself. As for salvific virtues, they are justice in a time of anger or pleasure, moderation in wealth or poverty, and fear of Allah in public and private. As for expiations, they are waiting for prayer in between prayers, thorough ablution on cold mornings, and walking to the congregations. As for rises in ranks, they are feeding the poor, spreading peace, and prayer at night while people sleep.
