Abu Hurairah (RadiyAllahu Anhu) reported: I heard Messenger of Allah (Sallellahu Alaihi Wa Sallam) saying, "He who is afraid of the pillage of the enemy, sets out in the early part of the night; and he who sets out early, reaches his destination. Be on your guard that the commodity of Allah is precious. Verily the commodity of Allah is Jannah".
Imam At-Taibi has stated that the Prophet (S.A.W.S.) mentioned this example for travellers to the Hereafter, because Satan is sitting on this passage and man's self and his false desires are his helpers. If a person is wide-awake in his travel and exercises caution in his activities, he is not only saved from the vices of Satan, but his own false desires also do not stand in his way. The Prophet (S.A.W.S.) also pointed out that the way to the Hereafter is very hard and littered with great impediments and obstructions and it is by no means easy to traverse it. Jannah is an invaluable gift and unless man gives the sacrifice of his life and wealth, he will not become eligible for entering it. "Allah has purchased the lives and properties of Muslims for Jannah".
This Hadith encourages us to observe obedience of our Rubb and to spare no effort to desist from all acts of disobedience in order to achieve the lofty goal of entering Jannah, by Allah's Leave.
