So fear Allāh as much as you are able and listen and obey and spend [in the way of Allāh]; it is better for your selves. And whoever is protected from the stinginess of his soul - it is those who will be the successful.
ٱلۡمُفۡلِحُونَ(are) the successful onesl-muf'liḥūna
Tafsir
So be mindful of Allah by fulfilling His instructions and avoiding His prohibitions as far as you can follow Him. Listen and follow Allah and His messenger. Spend your wealth, which Allah has provided to you, in avenues of good. Those whom Allah has protected from the greed of their souls, they are the ones who will attain what they desire and who will be saved from what they fear.
