janaab-i-Afzal SaaHib, aadaab
yaad-aavarii kaa bahut bahut shukriyah.
Thank you for posting this fine poem on Jaami3 Masjid Dehli. When I read it, like Khalid SaaHib, I too wondered who the poet was. I then thought you would have provided the poet's details, had you known them. I agree with Khalid SaaHib that it is good to know the poet's name. I also agree with you that, in the absense of this information, one need not dwell on the creator but on the creation! For what it's worth, I did try my level best to find the poet's name but alas, my "search powers" have greatly diminished!!
When I read the nazm, I too wondered why you had written the word as "chahaarrum". The double "r", I thought, is most likely to be a typo. Of course, I do not have the inside knowledge which you and Raj Kumar SaaHib have about such matters as "vazn". Otherwise, I would have not waited for Raj Kumar SaaHib to point out this defect!:-)
Now coming to your question. Can I ask you and Raj Kumar SaaHib, if writing it as "charx-i-chaarum" would put it in meter? I say this because this is how you found it and there is such a construction. This charx/sky (charx-i-chahaarum/chaarum - The fourth sky) is associated with Hazrat 'Isa (PBUH) and according to one source (Nur-ul-LuGhaat), the sun resides here. According to Urdu LuGhat it is "vuh aasmaan jis meN chaaNd kaa vujuud paayaa jaataa hai...ise Hazrat 'Isa se bhii manxuub kiyaa jaataa hai). So, take your pick!
A few examples that I have been able to locate in the depths of the net!:-)

You may know that Allaamah Ghulam Ahmed Parvez is know for his Qur'anic tafsiir "outside the box". Apparently, the Christians believed that Jesus (PBUH) was residing in the fourth sky/heavan and taunted the Muslims that their prophet lay in his grave in Madina! In his exposition of the Qur'an, chapter 3 vs 52-58 he mentions a na3t in which there is the following shi3r, which it seems is a response to the Christian taunt.
rah ga'e charx-i-chahaarum pih janaab-i-3iisaa
tai kiye haft samaavaat ke maidaan tuu ne
Ibn-i-Insha also has used this "tarkiib".
tum charx-i-chahaarum ke sitaare hu'e, logo
taaraaj karo zindagiyaaN ahl-i-jahaaN kii
(I hope I have copied this shi3r correctly)
