Glorify Allah And Be Of Those Who..

[Abu Hafsat]

As-Salaam alaikum, 

Abu Darda'i, may Allah be pleased with him, related that the Prophet, Sallallahu alaihi Wasallam, said :-

"Allah did not reveal to me to make trade of (with) Allah's Words or to collect (amass) wealth, but He revealed to me, 'But celebrate the Praises of your Lord and be of those who prostrate themselves in adoration" (Surah Hijr, 15:98) see Ibn Majah and ad-Daylami. 

Since it was not revealed to the Prophet, Sallallahu alaihi Wasallam, to accumulate money/wealth this indicates that it is not necessary for the whole Ummah to accumulate money over money, beyond one's needs. But we are all charged to "Praise Allah, Subhanahu Wa Ta'ala, and be from the people who make Sajda".
