Signs of the Learned Man

"... Another sign of the learned man of the next world is that he has got no attraction for various kinds of foods and drinks, luxury in dresses, furniture and houses, but rather he adopts moderate courses in all these things following the other sages and he is best satisfied with the least of everything. The less a man is attracted towards luxuries, the more he will be close to God and the more he will be in association of the learned men of the hereafter and in rank...

... In short, use of ornamentation in permissible things is not unlawful but it creates fondness for these and to give them up at the end becomes difficult..."

(Source: Imam Ghazali's Ihya Ulum-id-Deen)

Let us ponder:

The learning of the learned man goes back to whom?
The Companions of the Apostle of God.
The learning of the Companions goes back to whom?
The Apostle of God.

The Apostle of God erected palaces for himself where?
Not in this world.
The Companions erected palaces for themselves where?
Not in this world.

And so we ask:
Who is our master and our teacher?
The likes of Pharaoh and Namrud?
Nay, rather, in the Prophet of God do we find an excellent example, Sallallahu 3alayhi wa sallam.
