السلام عليكم ورحمة الله وبركاته ‎ أحسنَ اللهُ إليكم You Mentioned if we do istjimar we have to use 3 pieces, is this also the case if we use water afterwards? جزاك الله خيرا

When you do istijmar, use three pieces. If you need more, then use more, but stop on an odd number as we have mentioned. If you're going to wash, then washing is of course better and it would suffice, insha'Allah; there is no need for istijmar as well.
