Rabbana wa 'atina ma wa'adtana 'ala rusulika.. 

Our Lord! Grant us what Thou didst promise unto us through Thine apostles, and save us from shame on the Day of Judgment: For Thou never breakest Thy promise [3:194]
Rabbana wa 'atina ma wa'adtana 'ala rusulika wa la tukhzina yawmal-Qiyamah innaka la tukhliful mi'aad
