101 Dua: At the Time of wearing jewels
According to Imam Jafar Sadiq (as) the Holy Prophet (sa) used to wear the ring on the first finger and has prohibited wearing of ring on the middle finger.
According to Imam Jafar Sadiq (as) a ring should be worn at the very end of the finger where it joins with palm. According to Fiqhur-Riza one should recite the following prayer while wearing the ring:
Transliteration: ALLA-HOOMMA SAVIMNI BESIMAA'IL -IMANE, VAKHTIMLI BEKHAIRIN, WAJ'AL AA QEBATI ILA KHAIRIN INNAKA ANTAL AZIZOOL HAKEEMOOL KARIM
Oh Allah, let the signs of faith be the cause of my recognition! Let my end be worthwhile and let there be good for me even in the world to come. It is well-Known that Thou art All- Mighty, All-Wise and All-Generous!
It is sunnat to have a silver ring. Men are prohibited from wearing gold ring. Wearing iron, steel or brass ring is makrooh for both men and women. Therefore, according to Imam Jafar Sadiq (as), The Holy Prophet (sa) used to wear a silver ring.
According to another tradition The Holy Prophet (sa) asked men not to wear an iron ring while praying and strictly prohibited wearing of brass ring.
