Must a real estate seller invest his money solely in the real estate sector?

The narration "Whoever sells a house or property, let him know that it is wealth that is unlikely to be blessed for him, unless he invests it in something similar" is considered weak in its chain of transmission by some scholars, while Al-Albani graded it as hasan (definition) (good). Regardless of its authenticity, none of the scholars have made it obligatory to invest the proceeds of the sale in something similar; rather, it is a form of guidance. Ibn Uthaymeen mentioned that the evidence from Islamic law indicates that the hadith (definition) is not authentic, because a person has the freedom to dispose of their wealth as they wish.
