This is nothing but the word of a human being!
meaning, it is not the Words of Allah.
The person who is mentioned in this discussion is Al-Walid bin Al-Mughirah Al-Makhzumi. He was one of the chiefs of the Quraysh -- may Allah curse him. Among the narrations about this is what was reported by Al-`Awfi from Ibn `Abbas. He (Ibn `Abbas) said,
"Al-Walid bin Al-Mughirah entered the house of Abu Bakr bin Abi Quhafah and asked him about the Qur'an. When Abu Bakr informed him about it, he left and went to the Quraysh saying,
`What a great thing this is that Ibn Abi Kabshah is saying. I swear by Allah that it is not poetry, nor magic, nor the prattling of insanity. Verily, his speech is from the Words of Allah!'
So when a group of the Quraysh heard this they gathered and said,
`By Allah, if Al-Walid converts (to Islam) all of the Quraysh will convert.'
When Abu Jahl bin Hisham heard this he said, `By Allah, I will deal with him for you.'
So he went to Al-Walid's house and entered upon him. He said to Al-Walid, `Don't you see that your people are collecting charity for you'
Al-Walid replied, `Don't I have more wealth and children than they do'
Abu Jahl answered, `They are saying that you only went to Ibn Abi Quhafah's house so that you can get some of his food.'
Al-Walid then said, `Is this what my tribe is saying? Nay, by Allah, I am not seeking to be close to Ibn Abi Quhafah, nor `Umar, nor Ibn Abi Kabshah. And his speech is only inherited magic of old.'
So Allah revealed to His Messenger,
ذَرْنِي وَمَنْ خَلَقْتُ وَحِيدًا
.
لَاا تُبْقِي وَلَاا تَذَرُ
