Allah said,

﴿صِرَاطَ الَّذِينَ أَنْعَمْتَ عَلَيْهِمْ﴾

(The way of those upon whom you have bestowed Your grace), when He mentioned His favor. On mentioning anger, Allah said,

﴿غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ﴾

(Not (that) of those who earned Your anger), without mentioning the subject, although it is He Who has sent down the anger on them, just as Allah stated in another Ayah,

﴿أَلَمْ تَرَ إِلَى الَّذِينَ تَوَلَّوْاْ قَوْماً غَضِبَ اللَّهُ عَلَيْهِم﴾

(Have you (O Muhammad ) not seen those (hypocrites) who take as friends a people upon whom is the wrath of Allah (i.e. Jews)) (58:14).

Also, Allah relates the misguidance of those who indulged in it, although they were justly misguided according to Allah's appointed destiny. For instance, Allah said,

﴿مَن يَهْدِ اللَّهُ فَهُوَ الْمُهْتَدِ وَمَن يُضْلِلْ فَلَن تَجِدَ لَهُ وَلِيًّا مُّرْشِدًا﴾

(He whom Allah guides, he is the rightly-guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right path)) (18:17)

and,

﴿مَن يُضْلِلِ اللَّهُ فَلاَ هَادِيَ لَهُ وَيَذَرُهُمْ فِى طُغْيَـنِهِمْ يَعْمَهُونَ ﴾

(Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgression) (7:186).

These and several other Ayat testify to the fact that Allah alone is the One Who guides and misguides, contrary to the belief of the Qadariyyah sect, who claimed that the servants choose and create their own destiny. They rely on some unclear Ayat avoiding what is clear and contradicts their desires. Theirs, is the method of the people who follow their lust, desire and wickedness. An authentic Hadith narrated,

«إِذَا رَأَيْتُمُ الَّذِينَ يَتَّبِعُونَ مَا تَشَابَهَ مِنْهُ فَأُولئِكَ الَّذِينَ سَمَّى اللهُ فَاحْذَرُوهُمْ»

(When you see those who follow what is not so clear in it (the Qur'an), then they are those whom Allah has mentioned (refer to 3:7). Hence, avoid them.)

The Prophet was referring to Allah's statement,

﴿فَأَمَّا الَّذِينَ فى قُلُوبِهِمْ زَيْغٌ فَيَتَّبِعُونَ مَا تَشَـبَهَ مِنْهُ ابْتِغَآءَ الْفِتْنَةِ وَابْتِغَآءَ تَأْوِيلِهِ﴾

(So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials), and seeking for its hidden meanings)(3:7).

Verily, no innovator in the religion could ever rely on any authentic evidence in the Qur'an that testifies to his innovation. The Qur'an came to distinguish between truth and falsehood, and guidance and misguidance. The Qur'an does not contain any discrepancies or contradictions, because it is a revelation from the Most Wise, Worthy of all praise.
