What is the context of the hadith mentioned in question number (135085), is it specific to the night journey, and why was it used in this question despite there being no relation between it and the highest degree in Paradise?

The Hadith: "Whoever fears, sets out early; and whoever sets out early, reaches the destination. Verily, the commodity of Allah is expensive. Verily, the commodity of Allah is Paradise," is a good (hasan) and strange (gharib) hadith, authenticated by Al-Albani.

Its meaning: (Whoever fears): Refers to fearing an enemy. (Sets out early (adlja)): Flees at the beginning of the night, because the enemy raids at its end. (And whoever sets out early (adlja), reaches the destination): Whoever fears Allah should flee from sins to acts of obedience. (Verily, the commodity of Allah is expensive): The commodity of Allah is Paradise, which is of high value, and its price is nothing less than one's soul and wealth.

The intent of the parable: This hadith is a parable that illustrates that whoever desires salvation from the torment of the Hereafter and to attain Paradise, must flee from disobeying Allah to obeying Him, just as a traveler flees at the beginning of the night to escape from an enemy. Paradise is not attained easily, but through striving against one's self, overcoming whims, and abandoning desires. This is similar to the hadith: "Indeed, this religion is easy, and no one makes the religion difficult except that it overwhelms him. So, be straight and approximate, and receive good tidings, and seek help in the morning (Ghadwah) and the evening (Rawhah) and a part of the night (Duljah)."

In summary, whoever desires Paradise must exert good deeds and flee from sins to acts of obedience.
