As for those who establish a religion that Allah has not permitted, it is known that its fundamental principles, which necessitate it, cannot be transmitted from the Prophet, as it is false, and what is necessitated by falsehood is false, just as what is necessitated by truth is true.
This classification also highlights the intention of the Salaf and the Imams in condemning kalam and its people:
As this applies to those who use corrupt evidence or argue for false doctrines. But as for those who speak the truth that Allah has permitted in judgment and evidence, they are among the people of knowledge and faith. And Allah speaks the truth and guides to the right path.
As for addressing the people of a terminology with their terminology and language, it is not disliked - if there is a need for that and the meanings are correct -
like addressing non-Arabs:
from the Romans, Persians, and Turks in their language and customs, for this is permissible and good when needed. The Imams only disliked it when there was no need for it, and for this reason, the Prophet said to Umm Khalid, the daughter of Khalid ibn Sa'id ibn al-As - and she was a young girl born in the land of Abyssinia because her father was among the emigrants to it, so he said to her -
{O Umm Khalid, this is sana}
and sana in the Abyssinian language means good; because she was from the people of that language. Likewise, the Quran and Hadith are translated for those who need to understand them through translation, and likewise, a Muslim reads what he needs from the books of other nations and their speech in their language. And he translates them into Arabic. Just as the Prophet ordered Zaid ibn Thabit to learn the writing of the Jews to read it for him and write it for him because he did not trust the Jews regarding it.
الرَّسُولِ. وَأَمَّا مَنْ شَرَعَ دِينًا لَمْ يَأْذَنْ بِهِ اللَّهُ فَمَعْلُومٌ أَنَّ أُصُولَهُ الْمُسْتَلْزِمَةَ لَهُ لَا يَجُوزُ أَنْ تَكُونَ مَنْقُولَةً عَنْ النَّبِيِّ إذْ هُوَ بَاطِلٌ وَمَلْزُومُ الْبَاطِلِ بَاطِلٌ كَمَا أَنَّ لَازِمَ الْحَقِّ حَقٌّ.
وَهَذَا التَّقْسِيمُ يُنَبِّهُ أَيْضًا عَلَى مُرَادِ السَّلَفِ وَالْأَئِمَّةِ بِذَمِّ الْكَلَامِ وَأَهْلِهِ:
إذْ ذَلِكَ يَتَنَاوَلُ لِمَنْ اسْتَدَلَّ بِالْأَدِلَّةِ الْفَاسِدَةِ أَوْ اسْتَدَلَّ عَلَى الْمَقَالَاتِ الْبَاطِلَةِ. فَأَمَّا مَنْ قَالَ الْحَقَّ الَّذِي أَذِنَ اللَّهُ فِيهِ حُكْمًا وَدَلِيلًا فَهُوَ مِنْ أَهْلِ الْعِلْمِ وَالْإِيمَانِ. وَاَللَّهُ يَقُولُ الْحَقَّ وَهُوَ يَهْدِي السَّبِيلَ.
وَأَمَّا مُخَاطَبَةُ أَهْلِ اصْطِلَاحٍ بِاصْطِلَاحِهِمْ وَلُغَتِهِمْ فَلَيْسَ بِمَكْرُوهِ - إذَا اُحْتِيجَ إلَى ذَلِكَ وَكَانَتْ الْمَعَانِي صَحِيحَةً -
كَمُخَاطَبَةِ الْعَجَمِ:
مِنْ الرُّومِ وَالْفُرْسِ وَالتُّرْكِ بِلُغَتِهِمْ وَعُرْفِهِمْ فَإِنَّ هَذَا جَائِزٌ حَسَنٌ لِلْحَاجَةِ. وَإِنَّمَا كَرِهَهُ الْأَئِمَّةُ إذَا لَمْ يَحْتَجْ إلَيْهِ وَلِهَذَا قَالَ النَّبِيُّ لِأُمِّ خَالِدٍ بِنْتِ خَالِدِ بْنِ سَعِيدِ بْنِ العاص - وَكَانَتْ صَغِيرَةً وُلِدَتْ بِأَرْضِ الْحَبَشَةِ لِأَنَّ أَبَاهَا كَانَ مِنْ الْمُهَاجِرِينَ إلَيْهَا فَقَالَ لَهَا -
{يَا أُمَّ خَالِدٍ هَذَا سَنَا}
وَالسَّنَا بِلِسَانِ الْحَبَشَةِ الْحَسَنُ؛ لِأَنَّهَا كَانَتْ مِنْ أَهْلِ هَذِهِ اللُّغَةِ. وَكَذَلِكَ يُتَرْجَمُ الْقُرْآنُ وَالْحَدِيثُ لِمَنْ يَحْتَاجُ إلَى تَفْهِيمِهِ إيَّاهُ بِالتَّرْجَمَةِ وَكَذَلِكَ يَقْرَأُ الْمُسْلِمُ مَا يَحْتَاجُ إلَيْهِ مِنْ كُتُبِ الْأُمَمِ وَكَلَامِهِمْ بِلُغَتِهِمْ. وَيُتَرْجِمُهَا بِالْعَرَبِيَّةِ. كَمَا أَمَرَ النَّبِيُّ زَيْدَ بْنَ ثَابِتٍ أَنْ يَتَعَلَّمَ كِتَابَ الْيَهُودِ لِيَقْرَأَ لَهُ وَيَكْتُبَ لَهُ ذَلِكَ حَيْثُ لَمْ يَأْمَنْ مِنْ الْيَهُودِ عَلَيْهِ.
