I read one interesting analogy about this world being nothing but a shadow in Islahi Majalis Vol 4, by Mufti Taqi Usmani Sahab (may Allah be pleased with him).
Mufti Sahab says that the things that we usually seek in this world (power, wealth, fame etc) are nothing but like a shadow. If you run after your shadow it will run away from you and you would never be able to catch it. But if you run away from your shadow, it will keep on following you wherever you go.
Subhan Allah. What an example. If we can submit ourselves to the will of Allah, Allah makes all these worldly things to follow us like a shadow. Don’t you see many such men who have submitted to the will of Allah, sitting in a high chair and people with power, money, fame etc sitting in their feet. May Allah grant us the wisdom to pursue things which will make the life after death more pleasant and happy. Ameen.
