INTERESTING STORY!

Ibn ’Abdil Barr relayed in his explanation of "Al-Muwaṭṭa'" that Abū ’Ubaidah Al-Qāsim ibn Sallām raḥimahullāh said: "كنت أفتي أن من نام جالسا لا وضوء عليه حتى قعد إلى جنبي رجل يوم الجمعة، فنام، فخرجت منه ريح! فقلت: قم فتوضأ. فقال: لم أنم. فقلت: بلى، وقد خرجت منك ريح تنقض الوضوء! فجعل يحلف بالله ما كان ذلك منه، وقال لي: بل منك خرجت! فزالت ما كنت أعتقد في نوم الجالس، وراعيت غلبة النوم ومخالطته القلب." “I used to issue fatwa that whoever sleeps sitting does not have to perform wuḍhū', up until a man sat next to me one Friday, he then fell asleep and let out wind! So I said: Get up and perform wuḍhū'. He said: I did not sleep. So I said: Yes [you did], and you even let out wind which invalidates wuḍhū! So he started swearing by Allāh that it had not transpired from him, and he said to me: Rather, it came from you! From then on I gave up my view on the sleep of the one sitting and began to take into account the nature of deep sleep and its effect on the heart.” [end quote]
