When Hazrat Mirza Ghulam Ahmad (as), the Promised Messiah, passed away, he left behind three rings. 

The oldest was made in 1876, after the demise of his father; the ring with the inscription of the famous revelation

“Alaisallahu Bikafin ‘Abdahu”, meaning, Is Allah not Sufficient for His Servant?

The second ring was the one that Hazrat Ahmad (as) probably had made in, or around, 1892. That ring bears the revelation (c.1884), “Udhkur Ne’mati-Allati An‘amtu ‘Alaika. Gharastu Laka Biyadi Rahmati Wa Qudrati”, meaning, Remember My bounty that I bestowed upon you. I have planted for you a tree of My mercy and My power with My Own hand.

The third ring was the one that a companion of Hazrat Ahmad (as) gifted him a few years before his demise, in around 1906. This had engraved on it the words “Maula Bus”, meaning, God is sufficient.

Hazrat Mirza Bashir Ahmad M.A. (ra) wrote an article about these rings which was published in Al Fazl of 10 December 1945.
