Arabic (Original)
حَدَّثَنَا يَعْلَى 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 الْمُؤْمَنِ إِلَى نِصْفِ السَّاقِ فَمَا كَانَ إِلَى الْكَعْبِ فَلَا بَأْسَ وَمَا كَانَ تَحْتَ الْكَعْبِ فَفِي النَّارِ.
English Translation
Ya'la ibn 'Ubayd told us: Muhammad — meaning Ibn Ishaq — told us, from al-'Ala' ibn 'Abd al-Rahman, from his father, from Abu Sa'id al-Khudri, who said: The Messenger of God (peace and blessings be upon him) said: "The lower garment of the believer reaches to the middle of the shin; there is no harm in what reaches to the ankle, but what is below the ankle is in the Fire."
