Allah's statement,
﴿وَمَن يُشَاقِقِ الرَّسُولَ مِن بَعْدِ
مَا تَبَيَّنَ لَهُ الْهُدَى﴾
(And whoever contradicts and opposes the Messenger after the right path has been
shown clearly to him.) refers to whoever intentionally takes a path other than the
path of the Law revealed to the Messenger, after the truth has been made clear,
apparent and plain to him. Allah's statement,
﴿وَيَتَّبِعْ غَيْرَ سَبِيلِ الْمُؤْمِنِينَ﴾
(and follows other than the believers' way,) refers to a type of conduct that is
closely related to contradicting the Messenger . This contradiction could be in
the form of contradicting a text (from the Qur'an or Sunnah) or contradicting what
the Ummah of Muhammad has agreed on. The Ummah of Muhammad is immune from error
when they all agree on something, a miracle that serves to increase their honor,
due to the greatness of their Prophet. There are many authentic Hadiths on this
subject. Allah warned against the evil of contradicting the Prophet and his Ummah,
when He said,
﴿نُوَلِّهِ مَا تَوَلَّى وَنُصْلِهِ
جَهَنَّمَ وَسَآءَتْ مَصِيراً﴾
(We shall keep him in the path he has chosen, and burn him in Hell --- what an evil
destination!) meaning, when one goes on this wicked path, We will punish him by
making the evil path appear good in his heart, and will beautify it for him so that
he is tempted further. For instance, Allah said,
﴿فَذَرْنِى وَمَن يُكَذِّبُ بِهَـذَا
الْحَدِيثِ سَنَسْتَدْرِجُهُمْ مِّنْ حَيْثُ لاَ يَعْلَمُونَ ﴾
(Then leave Me Alone with such as belie this Qur'an. We shall punish them gradually
from directions they perceive not),
﴿فَلَمَّا زَاغُواْ أَزَاغَ اللَّهُ
قُلُوبَهُمْ﴾
(So when they turned away (from the path of Allah), Allah turned their hearts away),
and,
﴿وَنَذَرُهُمْ فِى طُغْيَانِهِمْ يَعْمَهُونَ﴾
(And We shall leave them in their trespass to wander blindly). Allah made the Fire
the destination of such people in the Hereafter. Indeed, the path of those who avoid
the right guidance will only lead to the Fire on the Day of Resurrection, as evident
by Allah's statements,
﴿احْشُرُواْ الَّذِينَ ظَلَمُواْ وَأَزْوَجَهُمْ﴾
((It will be said to the angels): "Assemble those who did wrong, together with their
companions (from the devils)), and,
﴿وَرَأَى الْمُجْرِمُونَ النَّارَ
فَظَنُّواْ أَنَّهُمْ مُّوَاقِعُوهَا وَلَمْ يَجِدُواْ عَنْهَا مَصْرِفًا ﴾
(And the criminals, shall see the Fire and apprehend that they have to fall therein.
And they will find no way of escape from there).
﴿إِنَّ اللَّهَ لاَ
يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذلِكَ لِمَن يَشَآءُ وَمَن يُشْرِكْ
بِاللَّهِ فَقَدْ ضَلَّ ضَلَـلاً بَعِيداً - إِن يَدْعُونَ مِن دُونِهِ
إِلاَّ إِنَـثاً وَإِن يَدْعُونَ إِلاَّ شَيْطَـناً مَّرِيداً - لَّعَنَهُ
اللَّهُ وَقَالَ لاّتَّخِذَنَّ مِنْ عِبَادِكَ نَصِيباً مَّفْرُوضاً -
وَلأضِلَّنَّهُمْ وَلأُمَنِّيَنَّهُمْ وَلاّمُرَنَّهُمْ فَلَيُبَتِّكُنَّ ءَاذَانَ
الاٌّنْعَـمِ وَلاّمُرَنَّهُمْ فَلَيُغَيِّرُنَّ خَلْقَ اللَّهِ وَمَن يَتَّخِذِ الشَّيْطَـنَ
وَلِيّاً مِّن دُونِ اللَّهِ فَقَدْ خَسِرَ خُسْرَاناً مُّبِيناً -
يَعِدُهُمْ وَيُمَنِّيهِمْ وَمَا يَعِدُهُمْ الشَّيْطَـنُ إِلاَّ غُرُوراً -
أُوْلَـئِكَ مَأْوَاهُمْ جَهَنَّمُ وَلاَ يَجِدُونَ عَنْهَا مَحِيصاً -
وَالَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ سَنُدْخِلُهُمْ جَنَّـتٍ تَجْرِى
مِن تَحْتِهَا الاٌّنْهَـرُ خَـلِدِينَ فِيهَآ أَبَداً وَعْدَ اللَّهِ حَقّاً وَمَنْ
أَصْدَقُ مِنَ اللَّهِ قِيلاً ﴾
(116. Verily, Allah forgives not (the sin of) setting up partners (in worship) with
Him, but He forgives whom He wills, sins other than that, and whoever sets up partners
in worship with Allah, has indeed strayed far away.) (117. They invoke nothing but
female deities besides Him (Allah), and they invoke nothing but Shaytan, a persistent
rebel!) (118. Allah cursed him. And he ﴿Shaytan﴾ said: "I will take an appointed
portion of your servants.") (119. "Verily, I will mislead them, and surely, I will
arouse in them false desires; and certainly, I will order them to slit the ears
of cattle, and indeed I will order them to change the nature created by Allah.''
And whoever takes Shaytan as a Wali instead of Allah, has surely suffered a manifest
loss.) (120. He ﴿Shaytan﴾ makes promises to them, and arouses in them false desires;
and Shaytan's promises are nothing but deceptions.) (121. The dwelling of such (people)
is Hell, and they will find no way of escape from it.) (122. And those who believe
and do righteous good deeds, We shall admit them to the Gardens under which rivers
flow (i.e. in Paradise) to dwell therein forever. Allah's promise is the truth;
and whose words can be truer than those of Allah)
