Ruling 542

If sidr leaves and camphor, or one of them, cannot be found, or if using them is not permitted – for example, they are usurped – then based on obligatory precaution a person must perform one tayammum on the deceased; and in place of whichever one was not possible [i.e. in place of the sidr leaves and/or camphor that could not be found or its use was not permitted], ghusl must be given with ordinary water.
