Saiyeduna Abdullah ibn Mas’ud (RA) has mentioned that Beloved Rasulullah ﷺ has said: Meaning: Verily before the final hour, people will only greet those that they know. Business would become so widespread and extensive that even the wife will [begin to] assist her husband in it [i.e. in amassing wealth]. Families will [begin to] cut off ties. People will [begin to] give false testimony, and those bearing the truth will [begin to] conceal it. [Finally,] Forgetfulness will also become so rampant that the people of knowledge will be forced into writing things down to preserve it.
