Hadith 981:54
Al-Hakam ibn Nafi’ narrated to us, Isma’il ibn ‘Ayyash narrated to us, from Habib ibn Salih, from Yazid ibn Shurayh al-Hadrami, from Abu Hayy the Mu’adhdhin, from Thawban, from the Messenger of Allah, peace and blessings of Allah be upon him, that he said: "It is not lawful for a man among the Muslims to look into the interior of a man’s house until he asks permission; if he looks, then he has entered. And let him not lead a people in prayer and single himself out with supplication to the exclusion of them; if he does so, then he has betrayed them. And let him not pray while he is suppressing the urge to urinate until he relieves himself."
حدثنا الحكم بن نافع، حدثنا إسماعيل بن عياش، عن حبيب بن صالح، عن يزيد بن شريح الحضرمي، عن أبي حي المؤذن، عن ثوبان، عن رسول الله صلى الله عليه وسلم أنه قال: " لا يحل لامرئ من المسلمين أن ينظر في جوف بيت امرئ حتى يستأذن، فإن نظر فقد دخل، ولا يؤم قوما فيختص نفسه بدعاء دونهم، فإن فعل فقد خانهم، ولا يصلي وهو حقن حتى يتخفف "
