Messenger of Allah (peace and blessings be upon him and his family) said: "Indeed, Allah (swt), the Blessed and Exalted, dislikes for you, O nation, twenty-four traits and has forbidden you from them. He (swt) dislikes frivolity during prayer, boasting in charity, laughing among graves, peeking into homes, and looking at the private parts of women." He (sw) said: "It leads to blindness." He (swt) has disliked speaking during intercourse. He (sw) said: "It leads to muteness." He (swt) has disliked sleeping before the last ('Isha) prayer and disliked talking after the last ('Isha) prayer. He (swt) has disliked bathing under the open sky without a loincloth, disliked intercourse under the open sky, and disliked entering rivers without a loincloth. He (sw) said: "There are inhabitants and dwellers from among the angels in the rivers." He (swt) has disliked entering bathhouses without a loincloth, disliked talking between the adhan and the iqamah for the morning prayer until the prayer is completed, disliked sailing in the sea during a storm, and disliked sleeping on a rooftop that is not enclosed." He (sw) said: "Whoever sleeps on a rooftop that is not enclosed, the protection (of Allah) is lifted from him." He (swt) has disliked a man sleeping alone in a house and disliked a man approaching his wife while she is in menstruation. If he does so and the child is born with leprosy or vitiligo, then he should blame none but himself. He (swt) has disliked a man approaching a woman after having experienced a wet dream until he has performed ghusl from the dream he saw. If he does so and the child is born insane, then he should blame none but himself. He (swt) has disliked a man speaking to a leper unless there is a distance of at least one arm's length between them. He (sw) said: "Flee from a leper as you would flee from a lion." He (swt) has disliked urinating on the bank of a flowing river and disliked relieving oneself under a fruit-bearing tree that has ripened, or a palm tree that has borne fruit. He (swt) has disliked putting on shoes while standing, disliked entering a dark house unless there is a lamp or fire in front of him, and disliked blowing (with the mouth) during prayer."
