The share of the Hereafter is for those who strive hard and fight, like the martyrs, and its great delight is greater than the share of anything in this worldly life. That is why Ibn Qutaibah said, "Lima yuhyikum" means martyrdom. According to some commentators, "Lima yuhyikum" means Paradise, for it is the home of life, and it is the eternal and good life. Narrated by Abu 'Ali Al-Jurjany.
The Qur'anic Verse examines all these aspects, for faith, Islam, the Qur'an and jihad provide hearts with a good life, and the perfect life is in Paradise. And the Messenger [ صلى الله عليه و سلم ] is inviting man to faith and Paradise. Therefore, he is inviting to the life of this world and the Hereafter.
Moreover, man cannot maintain two kinds of life. One part is the life of his body, with which he perceives that which is useful and that which is harmful. Whenever this element of life is weakened within him, he feels pain and weakness. That is why the life of the patient, the sad person, the grieved, the distressed, the feared, the poor and the debased, their life is inferior to the person who does not suffer from these things.
The second kind of life is that of his heart and soul, with which he can differentiate between truth and falsehood, between transgression and righteousness, and between guidance and being astray. He chooses the truth and leaves falsehood.
Therefore, this life gives him more benefit and more ability to distinguish between that which avails and that, which is harmful concerning knowledge, will and deeds. And it avails him with the power of faith, will, the love of truth, and the power of hatred against falsehood.
His feeling, perception, love and reluctance exist according to his share of this life. Just as the body that is full of life feels and perceives that which is useful and that which is harmful. It also perceives its inclination to what is useful, and it is reluctant about what is harmful. When the life of the heart comes to an end, its perception ceases to exist; it even cannot perceive that which is useful or harmful.
A man cannot live unless the angel breathes life into him in his mother's womb, and before that he was in a state like death. In the same way, there is no life for his spirit and heart unless the Messenger [ صلى الله عليه و سلم ] breathes into it the inspiration, which has been bestowed upon him.
Allah [ سبحانه و تعالى ] said,
يُنَزِّلُ الْمَلَائِكَةَ بِالرُّوحِ مِنْ أَمْرِهِ عَلَىٰ مَن يَشَاءُ مِنْ عِبَادِهِ أَنْ أَنذِرُوا أَنَّهُ لَا إِلَٰهَ إِلَّا أَنَا فَاتَّقُونِ
which means,
"He sends down the angels with the Rûh (Revelation) of His Command to whom of His slaves He wills (saying): "Warn mankind that Lâ ilâha illa Ana (none has the right to be worshipped but I), so fear Me (by abstaining from sins and evil deeds)."
