Ashab al-Suffa who spent their wealth andthemselves in the wayof Allah are exemplaryfor all Muslims

All the companions of our Prophet (saas) are examplary in their
superior morality and self-sacrifice. However especially those who
were called Ashab al-Suffa devoted 24 hours of their lives to Allah,
never got married,never pursued passions like family, children,
possessions or position; remained within the company of our Prophet
(saas) all the time and were educated by our Prophet (saas)
personally.
The companions of our Prophet (saas) who stayed in the antechamber
later annexed to the north part of Masjid al-Nabawi (the Mosque of our
Prophet (saas)) were referred as Ashab al-Suffa. They were those
blessed people who never married, had no relatives or attachment to a
tribe. They were not involved in trade and devoted all their time to
earn Allah's good pleasure and learn knowledge from our Prophet
(saas). Away from their families, they paid no attention to the
worldly deeds and continuously learned theQur'an and listened to our
Prophet's (saas) lectures and were sent to Muslim tribes to teach them
the Qur'an and the Sunnah. They were around 400-500 people and were
also known as the army of Wisdom.
Our Prophet (saas) was closely interested in their education.
These distinguished people who devoted themselves to Allah's way in
the true sense of the word, never missed the teachings of our Prophet
(saas). They were always ready there, memorized the teachings and
narrated them to other companions. It is told that the following verse
was revealed about Ashab al-Suffa (M.Hamdi Yazir, Hak Dini Kur'an
Dili, The Language of theQur'an, the Righteous Religion , 2/940)
It is for the poor who are held back in the Wayof Allah, unable to
travel in the land. The ignorantconsider them rich because of their
reticence. You will know them by their mark. Theydo not ask from
people insistently. Whatever good you give away, Allah knows it.
(Surat al-Baqara, 273)
The followers of Hazrat Mahdi (as) will, Insha'Allah, also spend
every moment of their lives in the way of Allah, they will never leave
Hazrat Mahdi (as ) and never dread from oppression and hardship.
Indeed, Insha'Allah together with Hazrat Mahdi (as), they will work
very hard to cause the morality of the Qur'an dominate the world.
