as God Almighty has said: ﴿وَإِذَا قِيلَ لَهُمْ تَعَالَوْا يَسْتَغْفِرْ لَكُمْ رَسُولُ اللَّهِ لَوَّوْا رُءُوسَهُمْ وَرَأَيْتَهُمْ يَصُدُّونَ وَهُمْ مُسْتَكْبِرُونَ﴾[1]; “And when it is said to them: ‘Come so that the Prophet of God may ask for forgiveness for you,’ they turned away their heads, and you saw them stopping (people) while acting arrogantly.” Yes, after the Prophet , it does not appear to be possible to go to him in order to request his du‘a and his asking for forgiveness from God, and therefore, there is no choice but to go to his Caliph for it, and therefore, it is obligatory for Muslims to go to his Caliph in their time and request him to pray and ask for forgiveness for them, and it is clear that his du‘a and his asking for forgiveness from God are in the same position as the du‘a of the Prophet and his asking for forgiveness from God.

Third; the sources of Islam

From what passed, it was made clear that Islam means submission to the will of God, and it is clear that the will of God has been manifested in His commands and prohibitions; because by virtue of His perfection, He has commanded everything that is useful for the human being’s perfection, prohibited from everything that leads to his imperfection, and communicated these commands and prohibitions to him through His Prophet. Therefore, the sources of Islam are things that the commands and prohibitions of God are known by referring to them, and they are the Book of God and His Prophet.

The Book of God

The first and most important source of Islam is the Book of God, which is the manifestation of His will in words, and it has been delivered to the heart of His Prophet with or without the mediation of an Angel, recited by His Prophet to hundreds of Muslims without addition or reduction, narrated by them to thousands of Muslims without any disruptive diversity, and passed on to the present Muslims in a written and mutawatir manner, and therefore, it is definitely proof.
