Sayyiduna Abu Bakrah (may Allah be pleased with him) narrates: It is disliked (makruh) for a man to urinate in the place where he bathes, because in this way he will be afflicted by misgivings (waswasah).
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, al-Salt bin Dinar, who is da'if (weak).
