“These are on (true) guidance from their Lord...
“These are on (true) guidance from their Lord, and they are the ones who are successful.” The Divine guidance is bestowed on the righteous ones, because guidance relates to the dignity of Lordship. Of course, felicity belongs to those who establish prayer, give poor-rate, and are certain of the Hereafter.
However, the Qur’an explains the end of the righteous as follows: “These are on (true) guidance from their Lord, and they are the ones who are successful.” The first sentence of the verse, from one side, shows that their guidance has been guaranteed from the side of their Lord and, from other side, the application of the word /‘ala/ (on) in this verse is an evidence for this fact that as if guidance were for them as a calm and level mount on which they are riding and have mastered it.
By this explanation, the difference between this guidance and the guidance mentioned at the beginning of the Surah is made clear, because the first guidance is the very preparation of accepting the truth, and this guidance is the program of reaching the destination.
By the way, the Qur’anic sentence: “They are the ones who are successful” which, according to the Arabic literature is a reference for its restriction, shows that the only way of felicity is this way which is the way of the good doers, the way of those who are in relation with Allah and the servants of Allah, and the way of those who have a perfect faith in both Origin and Resurrection.
“And there are, among men, those who purchase idle talk to lead (others) astray from the way of Allah without knowledge, and to take it in mockery; for these shall be a disgracing chastisement.” To invest capital for cultural attack and struggling against the truth surely has a long and vast precedent. Whatever exists opposite to wisdom is idle and it is a hinder for reaching to perfection.
