The passage quoted is :
Muhammad(saw) has once again descended among us And he is greater in status than before He who wishes to see Muhammad(saw) O Akmal Should see Ghulam Ahmad(as) in Qadian
This is totally a lie by the anti Ahmadis. Hazrat Mirza Ghulam Ahmad(as) never claimed such a thing rather this is a statement of Qadi Zaharud Din akmal. They cannot be associated with the Jamaat themselves.
Lets look at what Ahmad(as) said:
My life and heart are an offering for the graces of Muhammad(saw)
I am equal to the dust of the alleys belonging to the progeny of Muhammad(saw)
The poet himself states
“the aforementioned couplet is in great respect in the Court of Muhammad Mustafa (saw) (the Chosen One). God, who knows the hidden secrets hidden within the hearts, is witness that even my subconscious never considered any personality to be in any way comparable to the Seal of the Prophet(saw). Allah the Almighty knows better that by writing this couplet – ‘and he is greater in status than before’—I never imagined that I was bringing anyone in comparison with the Holy Prophet(saw). Rather, what I said was that Muhammad(saw) has descended—that is his second coming has taken place. This is the belief of all Ahmadi Muslims. It is neither by the way of incarnation nor by the transmigration of souls, but is the descent which is his spiritual manifestation as Allah has mentioned in the Holy Quran :
Surely every hour that follows is better for thee than the one that precedes.(Chapter 93 verse 5)
By virtue of durud sharif and noble deeds, not only is such a believer blessed, but the status of the Holy Prophet(saw) is also raised and would continue to be raised because there is no limit to God’s bounties. Therefore, I have said only that the blessings and munificence of Muhammad Mustafa(saw) are descending once again, and that his descent can only mean that his glory is being manifested more than ever before. No other person is mentioned in this couplet, in fact, the final couple of the poem is:
“that is Hazrat Mirza Ghulam Ahmad(as) has attained the status of the Promised Messiah as a consequence of his complete submission to, and perfect followership of , the holy Prophet Muhammad(saw) (Al Fazl, August 13, 1944)
We must remember here Akmal is the poet’s name so he is only saying that those who want to see the Prophet Muhammad (sa) can see him in Qadian, meaning his second coming. The spirituality of the Prophet Muhammad (sa) is always increasing through durood and it was never decrease.
In the time of Hadrat Musleh Maud (ra), he removed this couplet and apologized and Hadrat Musleh Maud (ra) said some people can misunderstand this.
Hadrat Musleh Maud (ra) has made it clear that anyone who thinks that Hadrat Ahmad (as) is greater is a disbeliever
