As-Salaam alaikum,
In a Hadith Qudsi, Allahu Subhanahu Wa Ta'ala, says:--

"For Me, the most blessed of My Friends is the person of faith who is unburdened
(by possessions), who takes pleasure in prayer, who carries out well his devotions
to his Lord and eagerly serves Him in secret. He is concealed among the people; no
one points him out. His sustenance is barely sufficient, and he is content with that.
His death comes quickly, there are few mourners, and his estate is small."

This Noble Hadith is included, with minor variations, in the canonical collections of Tirmidhi, Ibn Majah and Ibn Hanbal.
