It may happen that he made some achievement and is satisfied with what he has achieved in the past or at present. He never looks for further invention, production, and development thinking that what he achieved is the end of the journey and the highest degree of his striving, and efforts.

The third one feels that what he has of powers and energies are few and, also, thinks that his self, his hidden forces and his great ambition contain stored efforts and energies which wait for the following opportunities to blow them up. Such man continuously strives towards achieving what is best and most useful by considering each day that passes, a new opportunity and a new page on which a new achievement can be written.

Hence, taking care of the future is before the eyes of every man who is asked by the Almighty, Allah, to strive in the present world. Striving, as we all know, is considered a movement which is more energetic than regular walking. As it is a swift movement, it is, also, a purposeful movement aimed at achieving a certain purpose, and he searches for a result to his striving and activity: "And that there is not for man (aught) save what he strives for, and that his striving shall soon be seen.

Then shall he be recompensed to the fullest measure." Holy Qur'an (53:39-41) "And whoever intends for the hereafter and strives for it a (sincere) striving and he is a believer, these, their striving shall be (recompensed fully) accepted." Holy Qur'an (17: 19) Indeed, striving in a believing man's life, despite its being two strivings: one for the present world and the other for the hereafter, is considered as one (striving), particularly, for the one who contemplates well.

Because any striving in the present world, if it is done for man's welfare, his family, his society and his nation is, indeed, a striving in the way of the hereafter.

"And seek, with the means which Allah has given you, the Abode of the Hereafter, nor forget your portion in this world,…" Holy Qur'an (28:77) People, who have made wide and confident steps in the fields of science, art, economics, and culture, are those who have devoted their great attention (importance) for their future and who have never been satisfied with what their offspring have of bright and material or spiritual reality.
