ثُمَّ يُفِيضُونَ الْمَاءَ عَلَيْهِ، وَيُجَمَّرُ سَرِيرُهُ وِتْرًا
Translation: Then pour water over the body and perfume the washing bier with incense an odd number of times.
The water is poured over the body. The phrase yujammaru sariruhu witran describes perfuming the washing platform with incense an odd number of times. Incense is about fragrance; water is for washing.
