the secret of success is to obey Allah and his messenger ﷺ.
Dear Islamic brothers! In the Hereafter, successful is he who is obedient to Allah عَزَّوَجَلَّ and His Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم in spite of facing destitution, sickness and calamities. Listen to an admonitory narration and learn some lesson. (EXCELLENCE OF HUNGER, A Chapter of Faizan-e-Sunnat)
