IT is seemly that the servant should, after each prayer, supplicate God to bestow mercy and forgiveness upon his parents. Thereupon God's call will be raised: `Thousand upon thousand of what thou hast asked for thy parents shall be thy recompense!' Blessed is he who remembereth his parents when communing with God. There is, verily, no God but Him, the Mighty, the Well-Beloved.
VIII, 16.
