Assalamu 'alaikum, when I use the toilet I feel splash-back (not certain exactly where so I wash everything) and it's too hard to wash it off - i go in the tub (as staying on the toilet will cause even more splash-back) and it gets quite lengthy and tiring. What should I do to eliminate any splash-back and clean up. Jazakallah khayr.
Alaikumassalam wa rahmatullah,
Eliminating splash-back is an engineering problem that I cannot help with. You can search for “eliminate toilet splash” on Google and YouTube for many articles and videos about ways to eliminate it.
As for the religious part, according to some scholars it is sufficient to use a dry object, such as a piece of toilet paper, to clean the parts of your body that you think were hit by the splash. This opinion is mentioned by the editor of the Maliki compendium al-Sharḥ al-Ṣaghīr by the jurist al-Dardīr (d. 1786) on page 81, footnote 1. This opinion is also supported by a modern fatwa on the Qatari website IslamWeb which is operated by Qatar’s Islamic Affairs ministry (archived link in Arabic).
