Our true capital is recognition (admission) of Allah, Prophet Muhammad and the Progeny of Muhammad (peace be upon them) and good deeds. However, when man does not know himself, he will not pay attention to recognition and good deeds. Yet, when he faces death and all those things that were related to his body depart, he falls into the ocean of regret and sorrow. “I did not do anything for myself.” For such a person, the Holy Koran declares,
“I swear by time,
most surely man is in loss” (Al-Asr: 1-2).
In the Holy Koran Allah swears that O mankind you are all in loss, those human beings who have not recognized themselves.
“Except those who believe and do good, and enjoin on each other truth, and enjoin on each other patience” (Al-Asr: 3).
However, those who have accepted faith, meaning attained recognition of Allah, and do good deeds are not in loss; furthermore, those who preach the truth and are patient, meaning strive (jihad). By not recognizing Allah, man renders the purpose of his life material and transitory (temporary).
