How long must one wait after urinating before praying, and after praying before urinating?
Synopsis
The Mechaber rules one must wait the time equivalent to walking four cubits (amot) after urinating before praying, due to lingering drops. Similarly, after praying one must wait four amot before urinating, since the prayer is still on one's lips. The Aruch HaShulchan discusses the reason for the post-prayer waiting period and notes it applies to Torah study as well.
