Allāh never left the Prophet ﷺ in the lurch at any time.
The Hereafter is better for us than the worldly life.
Allāh promised to give the Prophet ﷺ in this world and the Hereafter until he would be content.
Never forget your humble beginnings and your difficult past. Use it to be a better person, and to do good to others.
Do not turn away the orphan.
Do not rebuke the questioner.
Do not forget the favours of Allāh upon you, and mention them when possible.
