This question asks: Which scripture is the source of (a particular verse)?
The answer given uses only one sentence to address it viz- "But as far as I know it's not found in any scriptures." (The other portions are not dedicated at all to answering the question)
Naturally, i flagged it as "not an answer". But it was rejected.
Question: How can this one liner (one liner in the sense that it is only this one sentence that is attempting to answer the question) be considered as an answer? Should it not be converted to a comment?
He can simply say in comment the same thing like i said here. To add the translation part is completely unwanted and is also taken from the link i shared earlier in this comment. The same link can also be found in this answer of mine which is again already linked to in the very first comment under OP's question.
NOTE:
1.The other parts that are there in the answer are not answering the question.
2. Moreover, the other portions are not really adding anything after my this comment (which was posted much earlier than the answer), from where one can get the translation. Anyways, OP is not asking for the translation of the verse here but it's scriptural source.
UPDATE:
If you see this comment of the answer provider, you'll see he is trying to justify his answer by saying that when answers are a simple Yes or a No, one can answer like that. He links me to this meta post.
Now, even this justification is flawed. because, here the answer is not a simple No. No one can claim that the answer is no.
The same point is also echoed in question asker's this comment:
Second, it is quite a sweeping statement to say that a verse is not found in any scripture at all! No one could have gone through ALL the extant scriptures to make that claim ever. The best someone can say is that he or she hasn't come across the verse anywhere
But even that best statement can not be accepted as an answer.
