The cornerstone of [all] depravities is jealousy. 22ـ رَأْسُ الرَّذائِلِ الحَسَدُ. The cause of depression is jealousy. 23ـ سَبَبُ الكَمْدِ الحَسَدُ. The weapon of ignobility is jealousy. 24ـ سِلاحُ اللُّؤْمِ اَلحَسَدُ. The worst thing that can accompany a person is jealousy. 25ـ شَـرُّ ما صَحِبَ المَرْءَ الحَسَدُ. Purify your hearts of jealousy, for it is a depressing enfeebler. 26ـ طَهِّرُوا قُلُوبَكُمْ مِنَ الحَسَدِ، فَإنَّهُ مُكْمِدٌ مُضْني.

Just as rust corrodes iron until it causes it to waste away, so too does jealousy corrode the body until it wears away. 27ـ كَما أنَّ الصَّدَأَ يَأْكُلُ الحَديدَ حَتّى يُفْنِيَهُ، كَذلِكَ الحَسَدُ يُكْمِدُ الجَسَدَ حَتّى يُفْنِيَهُ. Jealousy is not from the characteristics of the God-wary. 28ـ لَيْسَ الحَسَدُ مِنْ خُلُقِ الأتْقِياءِ. Jealousy towards a friend for the blessing [he has been endowed with] stems from low self-esteem.[^1] 29ـ مِنْ صِغَرِ الهِمَّةِ حَسَدُ الصَّديقِ عَلَى النِّعْمَةِ.

Woe be to jealousy, how fair it is! It starts off with its companion and then kills him. 30ـ وَيْحَ الحَسَدِ ما أعْدَلَهُ، بَدَأ بِصاحِبِهِ فَقَتَلَهُ. Do not be jealous of each other, for jealousy eats away the faith like fire consumes firewood; and do not have hatred for one another for this is severing [for the faith]. 31ـ لاتَحاسَدُوا فَإنَّ الحَسَدَ يَأْكُلُ الإيمانَ، كَما تَأْكُلُ النّارُ الحَطَبَ، وَلاتَباغَضُوا فَإنَّها الحالِقَةُ. There is no malady like jealousy. 32ـ لاداءَ كَالحَسَدِ.
