The Messenger of Allah sallallahu alaihe wassallam said to Aisha radiallahu anha: "If you commit a sin, then ask Allah for forgiveness and repent to Him, for if a person acknowledges his sin and repents, Allah will accept his repentance."
Imagine that you possess all the money you ever wanted and achieved all you dreams and fulfilled all your wishes, then you lost everything. You would weep and complain, and be filled with regret; you would bite your fingers in sorrow for what you have lost. So what about your life which is slipping away from you without you even realizing it?
Our life is precious jewel whose value cannot be measured in material terms. Every minute of our life that passes can never come back. These minutes are our capital in this world, with which we can buy whatever we want of the delights of Paradise. In one minute we can do a lot of good and earn much reward. In just one minute, by giving in charity, studying, memorizing, or striving to do good deeds, we can make sure that this minute of our life is not wasted. One minute may be recorded in our book of good deeds if we know how to make the most of it and take care of it.
The time is too precious to be wasted or neglected, limit your time with worthy efforts and righteous deeds that please Allah and benefit other people.
