Tha'laba ibn Abi Malik al-Qurazi reported that he rode to 'Abdullah ibn Suwayd, one of the Banu Haritha ibn al-Harith, to ask him about the three times of nakedness. 'Abdullah used to observe these times. Tha'laba said, "'Abdullah asked, 'What do you want?' I replied, 'I want to observe them.' He said, 'When I take off my garment at midday, none of my family who have reached puberty comes to me without my permission unless I call them. Nor do they do that when it is Fajr until people know that I have prayed, nor when I have prayed 'Isha' and removed my clothes so that I can sleep.'"
