In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Ibn Mas’ud [may Allaah be pleased with him] reported that Allaah’s Messenger [peace and blessings of Allaah be upon him] drew a line in the sand with his hand and he said, “This is the straight path of Allah”. Then, the Prophet drew lines to the right and left, and he said, “These are other paths, and there is no path among them but that a devil is upon it calling to its way”. Then the Prophet recited the Ayah [وَأَنَّ هَـٰذَا صِرَٲطِى مُسۡتَقِيمً۬ا فَٱتَّبِعُوهُ‌ۖ وَلَا تَتَّبِعُواْ ٱلسُّبُلَ – And verily, this is my Straight Path, so follow it, and follow not (other) paths]. [Surah Al-An’aam. Aayah 153] [Musnad Aḥmad 4423]

Allaah [The Most high] said: [وَعَلَى اللَّهِ قَصْدُ السَّبِيلِ وَمِنْهَا جَائِرٌ – And upon Allah is the responsibility to explain the Straight Path but there are ways that turn aside]. [Surah An-Nahl. Aayah 9]

Az-Zujaaj [may Allaah have mercy upon him] said: “It is Allaah who will clarify the straight path and call to it with Hujaj [clear and overwhelming proofs that defeats all the obstinate and stubborn ones] and Burhaan [proofs that clarify and distinguish between truth and falsehood in everything]. [وَمِنْهَا جَائِر -but there are ways that turn aside]: Ibn Abbaas [may Allaah be pleased with him and his father] said, “They are the different types of desires [i.e. evil desires]”. Ibnul Mubaarak [may Allaah have mercy upon him] said, “They are the (evil) desires and the innovations in religion”. [Zaadul Maseer Fee Ilmit Tafseer by Imaam Ibnul Jawzi]

Allaah [The Exalted] said:

أَفَمَن زُيِّنَ لَهُ سُوءُ عَمَلِهِ فَرَآهُ حَسَنًا ۖ فَإِنَّ اللَّهَ يُضِلُّ مَن يَشَاءُ وَيَهْدِي مَن يَشَاءُ ۖ فَلَا تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَاتٍ ۚ إِنَّ اللَّهَ عَلِيمٌ بِمَا يَصْنَعُونَ

Is he, then, to whom the evil of his deeds made fair-seeming, so that he considers it as good? Verily, Allah sends astray whom He wills, and guides whom He wills. So destroy not yourself (O Muhammad) in sorrow for them. Truly, Allah is the All-Knower of what they do! [Surah Al-Faatir. Aayah 8]

[أَفَمَن زُيِّنَ لَهُ سُوءُ – Is he, then, to whom the evil of his deeds made fair-seeming] -Meaning, his evil and repugnant deeds have been made fair-seeming to him by shaytaan and beautified in his eyes; [فَرَآهُ حَسَنًا – so that he considers it as good] -Meaning, considers his evil and repugnant deeds to be good like the one whom Allaah has guided to the straight;, but are the two the same? The first one commits evil deeds, considers truth to be falsehood and falsehood to be truth, and the second person performs good deeds, considers truth to be truth and falsehood to be falsehood. However, guidance is in the hands of Allaah, [ فَإِنَّ اللَّهَ يُضِلُّ مَن يَشَاءُ وَيَهْدِي مَن يَشَاءُ ۖ فَلَا تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَاتٍ – Verily, Allah sends astray whom He wills, and guides whom He wills. So destroy not yourself (O Muhammad) in sorrow for them]- Meaning, the misguided ones to whom their evil deeds are made fair-seeming and shaytaan hinders them from the truth. Therefore, there is nothing obligated on you (O Muhammad) except to convey the message and there is nothing on you regarding their guidance, rather Allaah is the one who will recompense them for their deeds. [ إِنَّ اللَّهَ عَلِيمٌ بِمَا يَصْنَعُونَ- Truly, Allah is the All-Knower of what they do]. [An Excerpt from Tafseer As-Sadi. Slightly paraphrased]
