عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ صَفْوَانَ الْجَمَّالِ عَنْ أَبِي حَمْزَةَ الثُّمَالِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ يَا أَبَا حَمْزَةَ الْوُضُوءُ قَبْلَ الطَّعَامِ وَ بَعْدَهُ يُذْهِبَانِ الْفَقْرَ قُلْتُ بِأَبِي أَنْتَ وَ أُمِّي يَذْهَبَانِ بِالْفَقْرِ فَقَالَ نَعَمْ يَذْهَبَانِ بِهِ.

2. Ali ibn Ibrahim has narrated from his father from Ahmad ibn Muhammad from ibn abu Nasr from Safwan al-Jammal from abu Hamzah al-Thumaliy who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, once said, ‘O abu Hamzah, Wudu (washing) before and after eating food removes poverty.’ I then said, I pray to Allah to keep my soul in service for your cause, does it remove poverty?’ He (the Imam) said, ‘Yes, it removes poverty.’”
