I’ve been told by elders and the resident aalim of my community that there’s a Hadith of Imam Ali that states that sweeping the house at night takes away sustenance. Is that true? They refrain us from cleaning the house after dinner time because of this Hadith that states it takes away sustenance. Is there such Hadith present?

If so, how come the shrines of our imams and their courtyards are majority of the time cleaned at night time.

In a nutshell there are no such narrations in fact we have narrations that speaks about leaving rubbish inside the house as a makrooh act.
