Hadith

Imam Reza (pbuh)

لاَ يَجْتَمِعُ اَلْمَالُ إِلاَّ بِخِصَالٍ خَمْسٍ بِبُخْلٍ شَدِيدٍ وَ أَمَلٍ طَوِيلٍ وَ حِرْصٍ غَالِبٍ وَ قَطِيعَةِ اَلرَّحِمِ وَ إِيثَارِ اَلدُّنْيَا عَلَى اَلْآخِرَةِ

Wealth can only be gathered through five means: through intense miserliness, high expectation, overcoming greed, cutting of kinship, and preferring this world over the Hereafter

Uyun Akhbar al-Rida (AS), v. 1, p. 276
