Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaihi) once mentioned:

Every moment of one’s life is extremely valuable. Hence, whatever time one finds to carry out righteous actions, one should value that time and utilize it profitably in carrying out good deeds. Nabi (sallallahu ‘alaihi wasallam) mentioned in the mubaarak hadeeth:

فليتزود العبد من نفسه لنفسه ومن حياته لموته ومن شبابه لكبره ومن دنياه لآخرته

“One should prepare provisions (for the journey of the Hereafter) through carrying out good deeds which will benefit him (in the Hereafter), and prepare through his life for his death, and through his youth for his old age, and through his dunya for his Aakhirat.” 

(Suhbate ba Awliyaa pg. 79)
