We will be taking the next two lines of poetry as they are related.
وقل غيرُ مخلوقٍ كلام مليكنا بذلك دان الـأتقياء وأفصحوا
3) And say: Not a created thing is the Speech of our great King,
Such was the religious position of the pious ones (before us) which they clearly expressed.
ولا تكُ في القرآن بالوقف قائلاً كما قال أتْباعٌ لِجَهْمٍ وأسححُوا
4) And do not be a person who takes no position on the Quran,
As did the followers of Jahm, and they had been too lax (to take the right position).
Question 3: For Brother Kashif
Sorry for the late reply,I was honestly,unable to understand this and had to contact a few friends in order to understand this,all I could come up with,is the following ::
The position of Ahlu U Sunnah wa Al Jam'ah is that Allaah Speaks when and how He wills , and that is opposing the position of Jahm and his followers who say the Quran is created .. we say the Quran is uncreated the true speech of Allaah.The Ja'ahm and his followers say it is created thats where they went astray in this regard.
In surat al kahf it says in translation:
Say, "If the sea were ink for [writing] the words of my Lord, the sea would be exhausted before the words of my Lord were exhausted, even if We brought the like of it as a supplement." Al kahf [18:109]
Allah says: `Say, O Muhammad, if the water of the sea were ink for a pen to write down the words, wisdom and signs of Allah, the sea would run dry before it all could be written down.
﴿وَلَوْ جِئْنَا بِمِثْلِهِ﴾
(even if We brought like it) means, another sea, then another, and so on, additional seas to be used for writing. The Words of Allah would still never run out. As Allah says:
﴿وَلَوْ أَنَّمَا فِى الاٌّرْضِ مِن شَجَرَةٍ أَقْلاَمٌ وَالْبَحْرُ يَمُدُّهُ مِن بَعْدِهِ سَبْعَةُ أَبْحُرٍ مَّا نَفِدَتْ كَلِمَـتُ اللَّهِ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ ﴾
(And if all the trees on the earth were pens and the sea (were ink), with seven seas behind it to increase it, yet the Words of Allah would not be exhausted. Verily, Allah is All-Mighty, All-Wise.) ﴿31:27﴾ Ar-Rabi` bin Anas said, "The parable of the knowledge of all of mankind, in comparison to the knowledge of Allah, is that of a drop of water in comparison to all of the oceans.'' Allah revealed that:
﴿قُل لَّوْ كَانَ الْبَحْرُ مِدَاداً لِّكَلِمَـتِ رَبِّى لَنَفِدَ الْبَحْرُ قَبْلَ أَن تَنفَدَ كَلِمَـتُ رَبِّى﴾
(Say: "If the sea were ink for the Words of my Lord, surely, the sea would be exhausted before the Words of my Lord would be finished,) Allah says that even if those oceans were ink for the Words of Allah, and all the trees were pens, the pens would be broken and the water of the sea would run dry, and the Words of Allah would remain, for nothing can outlast them. For no one can comprehend the greatness of Allah or praise Him as He deserves to be praised, except the One Who praises Himself. Our Lord is as He says He is and He is beyond what we can say. The blessings of this world, the beginning and end of it, in comparison to the blessings of the Hereafter, are like a mustard seed compared to the entire world.
﴿قُلْ إِنَّمَآ أَنَاْ بَشَرٌ مِّثْلُكُمْ يُوحَى إِلَىَّ أَنَّمَآ إِلَـهُكُمْ إِلَـهٌ وَاحِدٌ فَمَن كَانَ يَرْجُو لِقَآءَ رَبِّهِ فَلْيَعْمَلْ عَمَلاً صَـلِحاً وَلاَ يُشْرِكْ بِعِبَادَةِ رَبِّهِ أَحَدَا ﴾
(110. Say: "I am only a man like you. It has been revealed to me that your God is One God. So whoever hopes for the meeting with his Lord, let him work righteousness and associate none as a partner in the worship of his Lord.'')
Also the following two verses from surat an nisa supports that Qur'an the speech of Allah is not a created thing:
Allah - there is no deity except Him. He will surely assemble you for [account on] the Day of Resurrection, about which there is no doubt. And who is more truthful than Allah in statement.[4:87]
But the ones who believe and do righteous deeds - We will admit them to gardens beneath which rivers flow, wherein they will abide forever. [It is] the promise of Allah , [which is] truth, and who is more truthful than Allah in statement. an nisa[4:122]
These two verses imply that it is Allah's speech and not a created thing.
Sorry was difficult.Please correct me.
