Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا مُحَمَّدٌ يَعْنِي ابْنَ إِسْحَاقَ عَنِ الْعَلَاءِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِزْرَةُ الْمُسْلِمِ إِلَى نِصْفِ السَّاقِ فَمَا كَانَ إِلَى الْكَعْبِ فَلَا بَأْسَ وَمَا تَحْتَ الْكَعْبِ فَفِي النَّارِ.
English Translation
Muhammad ibn Ubayd told us: Muhammad - meaning Ibn Ishaq - told us, from al-Ala' ibn Abdur-Rahman, from his father, from Abu Sa'id al-Khudri, who said: The Messenger of Allah, peace and blessings be upon him, said, "The lower garment of the Muslim should reach the middle of the shin; what is between that and the ankle, there is no harm in it; and what is below the ankle is in the Fire."
