It is possible that a man traverse the Straight Path in the beginning of his life, then deviate from it and travel one of the paths of Shaytan, hence he is cut off from Allah and destroyed. “Indeed one of you will work the deeds of the denizens of the Fire and enter it.” (Bukhari)
Conversely it is possible that a person travel one of the paths of Shaytan in the beginning of his life and then good fortune come his way, and he traverse the Straight Path and thereby reach Allah. It is essential that a person firmly traverse the Straight Path from the beginning of the journey to the end,
“This is the bounty of Allah which he gives unto whom he will.” (al-Jummuah 62:4) “And Allah summons to the Abode of Peace, and leads whom He will to a Straight Path.” (Yunus 10: 25)
Many are the people who turn back after having travelled part of the journey and give up. The hearts are between two fingers of the fingers of the Al–Merciful (Muslim). “Allah confirms those who believe by a firm saying.” (Ibrahim 14: 27)
Those who falter in the path across the desert,
Are many, but those who reach the end are few.
