Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ عُبَيْدِ بْنِ عَقِيلٍ، قَالَ حَدَّثَنِي جَدِّي، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَشْعَثَ، قَالَ سَمِعْتُ سَعِيدَ بْنَ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ اللَّهَ عَزَّ وَجَلَّ لاَ يَنْظُرُ إِلَى مُسْبِلِ الإِزَارِ " .
It was narrated that Ash'ath said: "I heard Sa'eed bin Jubair narrate from Ibn 'Abbas that the Prophet [SAW] said: 'Allah will not look at the Musbil (the one who lets his Izar come below the ankles).'"
