Zayd ibn Jubayr stated that Prophet Muhammad (PBUH) said: “The best livelihood is the bare minimum.” Collected by Ahmad [S.J.S. 3275].
The Prophet (PBUH) instructed his followers to be in this world like a stranger or a traveler (Sahih Al-Bukhari, vol. 8 p. 284, no. 425). According to the Prophet (PBUH), it is best not to accumulate much property and wealth, because the more one has, the greater the responsibilities, temptations and distractions. Consequently, the best life is one based on the minimal material necessities.
