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

Allah, 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.’’ [16:9]

وَعَلَى اللَّهِ قَصْدُ السَّبِيلِ

“And upon Allah is the responsibility to explain the Straight Path”.

Az-Zujaaj, may Allah have mercy upon him, said:

It is Allah who will clarify the straight path and call to it with Hujaj [i.e. clear and overwhelming proofs that defeats all the obstinate and stubborn ones] and Burhan [i.e. proofs that clarify and distinguish between truth and falsehood in everything].

وَمِنْهَا جَائِر

“but there are ways that turn aside”

Ibn Abbas, may Allah be pleased with him and his father, said:

“They are the different types of (vain) desires”.

Ibn Al-Mubarak, may Allah have mercy upon him, said:

“They are the (vain) desires and the innovations in religion”.
