when you are 30 or 40 years old is the perfect time to look back upon your life, and ask yourself, what you have made of your life, what you have given, what you have taken...etc..
Its not the time to make mistakes, Its the timeto look back and learn...Its the time to teach, from what life has taught you, and start acting or being wise....
If when you are 40 or 50 you arent more loving, more giving, more caring, more in to thinking about the purpose of life, more in the remembrance of Allah, you should weep..and consider you life being wasted..But as each day is a new chance, there is still time to act on lifes knowledge...
Make up your mind today, to act wise even if you arent, It s likely to come with the acting...
May Allah gives us all a chance to repent, and be better human beings, better Muslims..
