‎Malik bin Dinar رحمه اللّه said: ‎إِنَّمَا الخَيْرُ في الشَّبَابِ. ‎“Certainly, goodness is almost exclusively during youth?” ‎Malik bin Dinar drew attention to this great point concerning the importance of this stage of life, and that if the young person utilizes it well, he will attain a great deal of good. What he acquires in his youth will become a base, a support, and a firm foundation that will remain with him until his death, serving as a benefit for himself and his community, and a means of sincere advice for others. ‎On the other hand, if he did not adequately do so, he would have wasted the goodness and blessing of this life stage for himself. When the prowess of youth, having idle time, and having readily available money coincide for the young person, this can be a cause of his destruction, as was once said: ‎إن الشَّبَابَ والفَرَاغَ والجَدَه ‎“Certainly, youth, idle time, and wealth” ‎مَفْسَدةٌ للمَرْءِ أَيُّ مَفْسَدَه ‎“Ruin a man in a most terrible fashion” ‎Additionally, when a fourth matter is added to the prowess of youth, free time, and ample wealth—namely, an abundance of trials that are in close proximity to the young person with many doors of access-then this is from the greatest destroyers for the young person, who, because of that, goes on to commit terrible offenses against the phase of youth, resulting in him missing out on its goodness and blessing. ‎So Malik bin Dinar used to say, ‎"Goodness is (almost) exclusively during youth," in order to draw attention to the great goodness and blessing of this life stage, so long as Allah سبحانه وتعالى guides the young person and aids him in utilizing it in a manner that pleases Him. ‎[Advice of the salaf to the youth pg. 17-18 by Shaykh Abdurrazzaq al-Badr حفظه الله]
