Hawzah News Agency – Imam Husayn peace be upon him says:

لَيست العِفَّةُ بِمانِعَةٍ رِزْقاً، ولا الحِرصُ بجالِبٍ فَضْلاً، وإنَّ الرِّزقَ مَقْسومٌ والأجَلَ مَحتومٌ، ؤاسْتِعمالُ الحِرصِ طَالبُ المَأْثَمِ.

'Self-restraint does not prevent [the descent of] sustenance, nor does covetousness attract any surplus [sustenance]; for indeed sustenance is allotted, and death is certain, and covetousness is only asking for sin.'
