✅ Answer: In an apparently Prophetic narration found in Jami' al-Akhbar by Shu'ayri, regarding leaving food containers unwashed, it is stated as follows:

1⃣قَالَ اَلنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَ آلِهِ:

عِشْرُونَ خَصْلَةً تُورِثُ اَلْفَقْرَ أَوَّلُهُ اَلْقِيَامُ مِنَ اَلْفِرَاشِ لِلْبَوْلِ عُرْيَاناً وَ اَلْأَكْلُ جُنُباً وَ تَرْكُ غَسْلِ اَلْيَدَيْنِ عِنْدَ اَلْأَكْلِ وَ إِهَانَةُ اَلْكِسْرَةِ مِنَ اَلْخُبْزِ وَ إِحْرَاقُ اَلثُّومِ وَ اَلْبَصَلِ وَ اَلْقُعُودُ عَلَى أُسْكُفَّةِ اَلْبَيْتَ.... وَ وَضْعُ اَلْقِصَاعِ وَ اَلْأَوَانِي غَيْرَ مَغْسُولَةٍ....

📚 Jami' al-Akhbar, p. 124

The Messenger of Allah (peace be upon him and his family) said: Twenty traits lead to poverty: The first is standing up naked from bed to urinate, eating while in a state of janabah, neglecting to wash hands before eating, disrespecting crumbs and pieces of bread, burning garlic or onion peels, sitting on the threshold or doorframe of a room... and leaving bowls and containers unwashed...!

✅ The above narration is not found in an authenticated form in earlier sources.

However, a similar narration is found in Al-Khisal by Sheikh Saduq, but some phrases, including the one related to the question, are not present!

However, in authentic narrations, washing containers is said to increase sustenance:

2⃣عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ یَحْیَی عَنْ أَبِیهِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ مُحَمَّدِ بْنِ عِیسَی عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ عَنْ مُحَمَّدِ بْنِ مَرْوَانَ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ: غَسْلُ الْإِنَاءِ وَ کَسْحُ الْفِنَاءِ مَجْلَبَةٌ لِلرِّزْقِ.

📚 Al-Khisal, p. 54

Imam Sadiq (peace be upon him) said: Washing containers and sweeping the courtyard and front of the house bring about sustenance!

اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْر
