Why Iqbal is craving in this shair?

Re: Why Iqbal is craving in this shair?

Considering Iqbal was pro sufism when he wrote that shair, “impatience of the seeker” is answer of ‘why’ then.

I am not denying the message in hadith but I would like to know what autority has made Ihsaan a dimension of Islam?
I am also unable to understand how could you imply unity of being from the verse and the hadith and/or the shair?
I wanted to reply your example of closer than jugular vein in another thread but that thread was closed dont know for what reason.
That verse refers to all-encompassing knowledge of Allah (s.w.t.) and does not imply physical closeness.

Although Iqbal remained pro sufism for some part of his life, but he was not one of proponents of unity of the being. He categorically declared that this idea is deadly poison for Ummah.
