All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
'Ali said: "I married Faatimah and I said: "O Prophet of Allaah, facilitate for me consummating my marriage." He said: "Give her something (i.e. dowry)." I replied: "I do not have anything to give her." He asked: "Where is your Hitami shield?" I said: “I still have it.” He said: "Give it to her." [Abu Daawood, At-Tirmithi, An-Nasaa'i]
'Ali said that the price of the shield was 400 Dirham (silver currency). [Al-Bayhaqi]. And the Arabic Dirham equals 2,975 g, therefore, the price of the shield in silver grams is 1190 g, and the price of the silver gram nowadays varies from one country to another.
