Success is defined here, and it is not your salary.
Guided now, successful in both worlds
After describing the believers, the verse gives the result. Ibn Kathir says they follow a light and insight from Allah, and are successful in this world and the Hereafter: they get what they seek and are saved from what they feared.
LinkedIn tells you success is a promotion. Instagram says it is a holiday. Your family may say it is a house. This verse quietly gives its own definition. Guided by your Lord, and safe at the end.
I will feel successful once I reach my career goals.
Being guided by my Lord is already success, whatever my job title says.
Write one line tonight: what would success look like if Allah were judging it?
