Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "I do not fear poverty for you, rather I fear abundance (of wealth and riches) for you. (And another thing is that) I do not fear that you will make mistakes unknowingly, rather I fear that you will commit sins deliberately."
