Word Khatam Used In An Arabic Couplet
There is only one verse and this is of a post-Quranic poet, therefore, its usage cannot be cited because, in principle, the classical use of the word is quoted from pre-Quranic kalam. The poet did not put the Arab (diacritical marks) because they were invented later. All the usage of the word Khatam, Khawateem, Khatma, indicate the end of something. The Quran used this word in different forms and all mean the end. So the word Khaatam in verse 33:40 gives no other meaning but the end. If someone insists that it has some other meaning, they need to provide evidence for their innovative idea.
As you mentioned sir,that poet didnt put aerab(diacritical marks )on it but rather katib has put it 1)if this is case,then can not we say that katib may have been impressed by Quranic usage. 2)you mentioned in your book that in whole kalam e arab only this is where khatam is supposed to be used as this. 3)why not hukum of tawatur can be said on it,as meaning of this from earlier times seems only one that last,as it has same mechanism of transmission as of Quran isnt it.
