It is a common allegation by members of the Qadiani Jamaat that when Maulana Muhammad Ali migrated from Qadian to Lahore at the time of the Split, he took with him to Lahore all the funds of the Sadr Anjuman Ahmadiyya, of which he was Secretary.
It so happened that looking in the issues of the Urdu edition of the Review of Religions, I found that every issue contains at the end accounts of the income and expenditure of the Sadr Anjuman Ahmadiyya for the previous month. Looking at some issues prior to the Split, I noticed that the accounts are signed off by the muhasib (accountant or auditor) whose name is given as Khalifa Rashid-udDin. This gentleman was father-in-law of Mirza Mahmud Ahmad, and after the Split he was in the Qadiani Jamaat. So here we find a prominent Qadiani keeping an eye on the accounts of the Sadr Anjuman Ahmadiyya even long before the Split!
The April 1914 issue does not present the accounts for March 1914, but the May 1914 issue (under control of the Qadiani Jamaat) presents accounts for both March 1914 and April 1914. I have extracted pages 193-194 and 195-196 of that issue showing these accounts for March and April. See this link.
The monthly accounts carry several headings such as education, the poor, school, propagation of Islam, etc. Under these headings there is a figure for the total of funds carried forward from the previous month (sabiqa baqaya), and then, after income and expenditure, the remaining total for the current month (baqaya).
In the end of March accounts I have marked in red all the baqaya entries, which are eight in all. In the end of April accounts I have marked in red all the eight sabiqa baqaya entries, i.e. the totals carried forward from end of March accounts to end of April accounts.
As far as I can see, each of these totals as it was at the end of March 1914, when Maulana Muhammad Ali was in Qadian, is exactly the same as the corresponding "carried forward" total at the end of April, by which time Maulana Muhammad Ali had left Qadian and these funds were in the hands of the Qadiani Jamaat!
This, if I am right, is absolute and positive proof, coming from a Qadiani Jamaat publication, that all the funds of the Sadr Anjuman Ahmadiyya remained with the Qadiani Jamaat after Maulana Muhammad Ali left Qadian, and he took nothing. Praise be to Allah, that He enabled us to find such clear proof!
