Arabic (Original)
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْوَلِيدِ حَدَّثَنَا سُفْيَانُ قَالَ حَدَّثَنِي سَلَمَةُ بْنُ وَرْدَانَ قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قُلْ يَا أَيُّهَا الْكَافِرُونَ رُبُعُ الْقُرْآنِ وَإِذَا زُلْزِلَتْ الْأَرْضُ رُبُعُ الْقُرْآنِ وَإِذَا جَاءَ نَصْرُ اللَّهِ رُبُعُ الْقُرْآنِ.
English Translation
'Abdullah ibn al-Walid narrated to us: Sufyan narrated to us, saying: Salama ibn Wardan narrated to me, saying: I heard Anas ibn Malik say: The Messenger of Allah, peace and blessings be upon him, said: "'Say, O disbelievers' equals a quarter of the Qur'an; 'When the earth is shaken' equals a quarter of the Qur'an; and 'When the help of Allah comes' equals a quarter of the Qur'an."
