Man has different thoughts in his mind every second and the friends, enemies, relatives, aliens, devils, and others, tempt him, threaten him, and encourage him to do things, which may or may not be in his interest in this world and the next.
Only with divine help can one chose the best, find the path to salvation and take the Straight Path.
The Straight Path is:
The path of God and His friends,
The path that is away from any deviation and wrongdoing,
The path whose guide loves me and knows what I need,
The path that leads to paradise.
The path that is in harmony with my healthy Fitrat (nature),
The path dying in which would be considered as martyrdom,
The path which comes from the upper world and is beyond our knowledge,
The path in which no one will become remorseful,
The path which is straighter, closer and lighter than all other paths,
And one that is the path of divine messengers, martyrs, the righteous and the pious.
These are the signs of the Straight Path. Knowing the path is difficult and moving on this path with steadfastness requires divine help.
