This is because the implementation of Islamic hudud by them is obligatory as part of establishing the entirety of Islam, and establishing the entirety of Islam by them is possible by following a person who possesses knowledge of the entirety of it. Such a person, as has been made clear, is Allah’s caliph on the Earth, to whom He has given the knowledge of the entirety of Islam and who serves as His intermediary in exercising His governance.

The Reality of the Non-Establishment of Islam

From the foregoing, it is understood that Islam has not been established after the time of the Messenger of Allah until now. This is an undeniable and evident reality; because for various causes, its original form and entirety have not found the opportunity to be established. Accordingly, as long as this situation persists, Muslims cannot attain happiness or deliverance from problems. Therefore, knowing the causes of this situation and the reasons for deviating from the original form and the entirety of Islam is beneficial for returning to the pure and perfect Islam, in the sense of its establishment after its loss. This is because it is clear that Muslims—by virtue of their divine nature and human disposition, as well as their affection for Islam—in principle have desired the establishment of the original form and the entirety of Islam. Thus, their failure in this endeavor has not been possible except as a result of the impediments that arose after the time of the Messenger of Allah . Yes, the passing of the Messenger of Allah and his absence has been a great calamity with terrifying consequences; as Allah had informed about it, saying: ﴿وَمَا كَانَ اللَّهُ لِيُعَذِّبَهُمْ وَأَنْتَ فِيهِمْ﴾[1]; “And Allah will not punish them while you are among them,” and: ﴿أَفَإِنْ مَاتَ أَوْ قُتِلَ انْقَلَبْتُمْ عَلَى أَعْقَابِكُمْ ۚ وَمَنْ يَنْقَلِبْ عَلَى عَقِبَيْهِ فَلَنْ يَضُرَّ اللَّهَ شَيْئًا ۗ وَسَيَجْزِي اللَّهُ الشَّاكِرِينَ﴾[2]; “So if he dies or is killed, will you turn back to your old ways?! While whoever turns back to his old ways will not harm Allah at all. And Allah will reward the grateful.”
