Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادٌ أَخْبَرَنَا عَلِيُّ بْنُ زَيْدٍ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ أَسْوَأَ النَّاسِ سَرِقَةً الَّذِي يَسْرِقُ صَلَاتَهُ قَالُوا يَا رَسُولَ اللَّهِ وَكَيْفَ يَسْرِقُهَا قَالَ لَا يُتِمُّ رُكُوعَهَا وَلَا سُجُودَهَا.
English Translation
Affan told us: Hammad told us: Ali ibn Zayd informed us, from Sa'id ibn al-Musayyab, from Abu Sa'id al-Khudri, that the Messenger of Allah, peace and blessings be upon him, said, "The worst of people in theft is the one who steals from his own prayer." They said, "O Messenger of Allah, how does he steal from it?" He said, "By not completing its bowing and its prostration."
