`Be content with your provision in this world…
Al-Hasan Al-Basri said: “Umar bin Al-Khattab wrote this letter to Abu Musa Al-Ash`ari:
`Be content with your provision in this world, for the Most Merciful has honored some of His servants over others in terms of provision as a test of both. The one who has been given plenty is being tested to see if he will give thanks to Allah and fulfill the duties which are his by virtue of his wealth…”’
It was reported by Ibn Abi Hatim.
