and if there is an imperfection in it that has caused the imperfection of Muslims, it has not originated from God but from Muslims themselves; because they have taken some parts of Islam and abandoned some parts of it and not established the entirety of it perfectly, while God has explicitly warned against that and said: ﴿أَفَتُؤْمِنُونَ بِبَعْضِ الْكِتَابِ وَتَكْفُرُونَ بِبَعْضٍ ۚ فَمَا جَزَاءُ مَنْ يَفْعَلُ ذَلِكَ مِنْكُمْ إِلَّا خِزْيٌ فِي الْحَيَاةِ الدُّنْيَا ۖ وَيَوْمَ الْقِيَامَةِ يُرَدُّونَ إِلَى أَشَدِّ الْعَذَابِ ۗ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ﴾[1]; “Do you believe in a part of the Book and disbelieve in another part?! What is the punishment for one among you who does so other than humiliation in the life of the world, and that they will be returned to the severest punishment on the Day of Judgment?! And God is not unaware of what you do.” It is clear that the humiliation of Muslims in the life of the world is the result of this selective action in Islam, and therefore, their return to the severest punishment in the Hereafter is inevitable according to the promise of God. As God has explicitly threatened those who have a discriminatory approach in the field of religion, and considered it not permissible to practice some parts of the Quran without some others and said: ﴿كَمَا أَنْزَلْنَا عَلَى الْمُقْتَسِمِينَ ۝ الَّذِينَ جَعَلُوا الْقُرْآنَ عِضِينَ ۝ فَوَرَبِّكَ لَنَسْأَلَنَّهُمْ أَجْمَعِينَ ۝ عَمَّا كَانُوا يَعْمَلُونَ﴾[2]; “As We sent down on dividers; those who divide the Quran into parts; then by your Lord! We will surely question them all; about what they used to do”; but rather He has considered His Prophet to have no concern with those who have divided their religion and not established the entirety of it as a non-degradable unit, and said: ﴿إِنَّ الَّذِينَ فَرَّقُوا دِينَهُمْ وَكَانُوا شِيَعًا لَسْتَ مِنْهُمْ فِي شَيْءٍ ۚ إِنَّمَا أَمْرُهُمْ إِلَى اللَّهِ ثُمَّ يُنَبِّئُهُمْ بِمَا كَانُوا يَفْعَلُونَ﴾[3]; “Indeed, those who divided their religion and became groups, you have no concern with them! Their affair is only with God, then He will inform them of what they used to do.”

As a result, the establishment of Islam leads to the realization of happiness and salvation from problems if it is established entirely as a single ruling; considering that Islam is, in fact, a single ruling, and the parts existing in it are like the parts existing in a device that, despite their multiplicity, constitute one device,
