In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Due to the greatness of truthfulness and its status in the sight of Allaah, the Muslims and those who possess sound intellect amongst humankind, Allaah described himself as one who is truthful. Allaah [The Exalted] said:
[قُلْ صَدَقَ اللَّهُ فَاتَّبِعُوا مِلَّةَ إِبْرَاهِيمَ حَنِيفًا وَمَا كَانَ مِنَ الْمُشْرِكِينَ – Say (O Muhammad): “Allah has spoken the truth; follow the religion of Ibrahim (Abraham) Hanifa (Islamic Monotheism, i.e. he used to worship Allah Alone), and he was not of the polytheists]. [Surah Aal Imran. Aayah 95]
This is praise – with this great description- given by Allaah to himself, because He is truthful in all of His reports, speech and legislation, in what He narrated about the Prophets and their nations, and in what he narrated about the Children of Israel, their prophets, believers, sinners and those who disbelieved among them, and about their distortion of Allaah’s Book – the Tawraat and the Injeel, and that they took the rabbis and monks as lords besides Allaah. (see footnote 1)
Allaah [The Exalted] said: [وَمَنْ أَصْدَقُ مِنَ اللَّهِ حَدِيثًا – And who is truer in statement than Allah?] [Surah An-Nisaa. Aayah 87] Allaah [The Exalted] said: [وَعْدَ اللَّهِ حَقًّا وَمَنْ أَصْدَقُ مِنَ اللَّهِ قِيلاً – Allah’s Promise is the Truth, and whose words can be truer than those of Allah? (Of course, none)]. [Surah An-Nisaa. Aayah 122]
Allaah [The Exalted] said:
وَمَا أَرْسَلْنَا قَبْلَكَ إِلَّا رِجَالًا نُوحِي إِلَيْهِمْ فَاسْأَلُوا أَهْلَ الذِّكْرِ إِنْ كُنْتُمْ لا تَعْلَمُونَ
وَمَا جَعَلْنَاهُمْ جَسَدًا لَا يَأْكُلُونَ الطَّعَامَ وَمَا كَانُوا خَالِدِينَ
ثُمَّ صَدَقْنَاهُمُ الْوَعْدَ فَأَنْجَيْنَاهُمْ وَمَنْ نَشَاءُ وَأَهْلَكْنَا الْمُسْرِفِينَ
And We did not sent before you (O Muḥammad) except men to whom We revealed (scripture), so ask the people of the (prior) remembrance if you do not know. (a) And We did not create them (the Messengers, with) bodies that ate not food, nor were they immortals; then We fulfilled to them the promise, and We saved them and those whom We willed, but We destroyed Al-Musrifun (i.e. extravagants in oppression, polytheism and in sin). (b) [Surah Al-Anbiyaa. Aayaat 7-9]
Allaah [The Exalted] said: [ذَلِكَ جَزَيْنَاهُمْ بِبَغْيِهِمْ وَإِنَّا لَصَادِقُونَ – Thus We recompensed them for their rebellion (committing crimes like murdering the Prophets, consuming Riba- usury, etc.). And verily, We are Truthful]. [Surah Al-An’aam. Aayah 146]
This is how Allaah described Himself with this great description- truthfulness in statements, deeds, promises and warning; truthfulness in the news about His prophets, loyal believers and His disbelieving enemies. And Allaah described His Prophets as truthful, supported them with miracles and great signs that proves their complete truthfulness and refuted the fabrications and denials of their enemies. And among the greatest things He supported them with was the destruction of their enemies with a flood, some of them with a furious violent wind, some were seized by the blast (from the sky) and swallowed by the earth, and some of them by way of drowning, whilst Allaah saved the prophets and their followers. All of this is from the Lord of the entire existence, a testimony to the truthfulness of His Prophets and that they are truly His Messengers, and a humiliation against His enemies and their enemies.
Among those described in the Qur’an with this description were Ibraaheem, Ismaa’eel and Idrees [peace and blessings be upon them]. Allaah [The Exalted] said: [وَاذْكُرْ فِي الْكِتَابِ إِبْرَاهِيمَ إِنَّهُ كَانَ صِدِّيقًا نَبِيًّا – nd mention in the Book (the Quran) Ibrahim (Abraham). Verily! He was a man of truth, a Prophet]. [Surah Maryam. Aayah 41]
Allaah [The Exalted] said: [وَاذْكُرْ فِي الْكِتَابِ إِسْمَاعِيلَ إِنَّهُ كَانَ صَادِقَ الْوَعْدِ وَكَانَ رَسُولاً نَبِيًّا -And mention in the Book (the Quran) Isma’il (Ishmael). Verily! He was true to what he promised, and he was a Messenger, (and) a Prophet]. [Surah Maryam. Aayah 54]
Allaah [The Exalted] said: [وَاذْكُرْ فِي الْكِتَابِ إِدْرِيسَ إِنَّهُ كَانَ صِدِّيقًا نَبِيًّا – And mention in the Book (the Quran) Idris (Enoch). Verily! He was a man of truth, (and) a Prophet]. [Surah Maryam. Aayah 56]
The description of truthfulness given to them is a statement regarding their ability to possess this quality, and that their statements, actions, promises and covenants are based on truthfulness.
And every Aayah in the noble Qur’an – a miracle with which the jinn and humankind are challenged to come up with a Surah like it, but they are unable to do so, is the greatest proof of his truthfulness and that he is truly Allaah’s Messenger and the Seal of the Prophets; and Allaah’s testimony for him that he is the Seal of the Prophets is a great miracle and a clear proof that Muhammad [peace and blessings of Allaah be upon him] is Allaah’s Messenger.
None has ever claimed prophethood after him, except that Allaah exposed him, disgraced, and revealed his defects and lies; rather, no one lied about him in a statement attributed it to his message, except that Allaah exposed and disgraced him through the explanation of the truthful followers of his message amongst the scholars of hadeeth and others. (Allaah) The Exalted stated – in praising him and for what he brought of truth and truthfulness – [بَلْ جَاءَ بِالْحَقِّ وَصَدَّقَ الْمُرْسَلِينَ – Nay! he (Muhammad) has come with the truth (i.e. Allah’s Religion – Islamic Monotheism and this Quran) and he confirms the Messengers (before him who brought Allah’s religion – Islamic Monotheism)]. [Surah As-Saffaat. Aayah 37]
This is the greatest status given to Allaah’s slave and His Messenger Muhammad [peace and blessings of Allaah be upon him]. [End of quote] Source https://www.mimham.net/tan-1308-82 slightly paraphrased. To be continued…InShaaAllaah
Footnote 1: Shaikh Abu Khadeejah [may Allaah preserve him] wrote in one of his lessons on Kitaab at-Tawheed with the explanation of Al-Allaamah ahmad Bin Yahyah An-Najmi [may allaah have mercy upon him]:
اتَّخَذُوا أَحْبَارَهُمْ وَرُهْبَانَهُمْ أَرْبَابًا مِّن دُونِ اللَّهِ
They have taken their “ahbaar” and “ruhbaan” as lords besides Allah.. [at-Tawbah: 31]
The “Ahbaar” are the scholars, and the “Ruhbaan” are the general worshippers – and the habit of the people is to refer back to these two groups and take to their speech and opinions. Allaah, the Mighty and Majestic, rebuked the unbelievers because they took the Ahbaar and Ruhbaan (the scholars and worshippers) as Lords besides Allaah whereby they made them as legislators of Religious Law (i.e. the Revelation). They would make halaal for them that which Allaah had made haraam, so they would then consider it to be halaal. And they would make haraam for them that which Allaah had made halaal, so they would then consider it to be haraam. This however does not necessitate, in an absolute sense, exiting from Islaam, rather this point it requires further explanation. So sometimes the one who falls into this reaches the point whereby he exits Islaam, and this is when they take them as legislators of Religious Law (i.e. the Revelation). So they take their legislation and they give it precedence over an above that which Allaah has legislated in His Book, and that which the Messenger (sallallaahu ‘alaihi wassallam) legislated, and they believe that this legislation that is not from Allaah and His Messenger is equal to Allaah’s Legislation or an increase upon it.
However, if they seek verdicts (fatwas) from them and they issue fatwas making haraam what is halaal, or making halaal what is haraam. So they obey them in making haraam the halaal matters, and making halaal the haraam matters by way of acting upon those verdicts – and the people obey them whilst they know they are sinning and they affirm the fact that it is a sin, yet they still follow them but they know internally what is halaal is halaal and what is haraam is haraam. This is then a major sin. https://abukhadeejah.com/ahmad-an-najmees-kitaab-at-tawheed-chapter-5-the-explanation-of-tawheed-and-the-shahaadah-laa-ilaaha-illallaah/
