وعن أبى هريرة رضى الله عنه
قال: بينما رجل يصلى مسبل إزاره، قال له رسول الله صلى الله عليه وسلم: «اذهب فتوضأ«فذهب فتوضأ، ثم جاء فقال: «اذهب فتوضأ«فقال رجل يا رسول الله ما لك أمرته أن يتوضأ ثم سكت عنه؟ قال: «إنه كان يصلى وهو مسبل إزاره، وإن الله لا يقبل صلاة رجل مسبل»
The Messenger of Allah (sallallahu alayhi wa sallam) said to a man who was performing Salah while his lower garment was trailing, “Go and perform your Wudu again.” The man went and came back having performed it.
The Messenger of Allah (sallallahu alayhi wa sallam) said (again), “Go and perform your Wudu.” Someone present said to the Messenger of Allah (sallallahu alayhi wa sallam): “O Messenger of Allah! You ask him to perform his Wudu and then you kept silent (without saying the reason for it).”
He (sallallahu alayhi wa sallam) said, “He performed Salah while his lower garment was below his ankles. Allah does not accept the Salah of a man who trails his lower garment.”.
