The literal meaning of destiny is to estimate, to determine, according to the Shari'ah, the meaning of this is that whatever is happening in the world, every moment is coming to the fore, all this is happening by the will of Allah, ie by His will, from the creation of this world. Thousands of years ago, it was decided by Allah and according to what was written in the Tablet, death, life, honor and disgrace, poverty and wealth, health and disease, happiness and misfortune, guidance and misguidance are all things determined by Him.
At first glance, one gets confused and lost in this issue, so this issue is a very delicate issue of Shari'ah, and its excessive digging and contemplation in it is undesirable and forbidden, just believe that it is from Allah. It is certain that as soon as this thought and belief settles in the heart of man, he gets so much peace and contentment that we are the servants of Allah and these conditions are coming from Him.
Briefly understand that Allah Almighty has divided the whole system of the universe into two parts, one part is what He is doing only by doing it and through the angels, human beings have no involvement in it, like the movement of winds Rain, growth of flowers, birth of all creatures, etc.
The second part is that which is related to human beings, that is, human deeds which man performs with his hands, feet and other limbs. DoIn any case, the destiny is that whatever is to happen in the world is predetermined by Allah. When a human being is born in this world, his food and drink, life and death are all predestined and there is no change in the destiny. There are two parts to it, one is called the predestined destiny and the other is called the predestined destiny. If a person is accustomed to goodness, his life span is increased and his "destiny" which is absolutely definite and is not changed for any reason.
According to the details mentioned in the Holy Qur'an and the hadiths of the Holy Prophet, there are four stages of human life, the first stage is the world of souls where it resides before it enters the mother's womb, the second stage is the world of bodies ie the world where it is in the mother's womb. From the time of coming to death, the third stage is the world of Barzakh, that is, the world between this world and the hereafter, where he has to live from death until the Day of Resurrection۔
And it will never end. In the spirit world there is only the soul, in the physical world there is the body with the soul, in the world of Barzakh according to the researchers there is only the soul of the common people and the body perishes, yes the bodies of special servants are also preserved. Like the prophets, saints, martyrs, in the world of the hereafter both the soul and the body will be reunited, but the difference between the body of this world and the body of the hereafter is that the body of this world is affected by different things and eventually disappears, decays and the body of the hereafter It will not change or end.
