Arabic (Original)
حَدَّثَنَا هَارُونُ بْنُ مَعْرُوفٍ أَخْبَرَنِي ابْنُ وَهْبٍ أَخْبَرَنَا يَزِيدُ بْنُ عِيَاضٍ عَنْ عِمْرَانَ بْنِ أَبِي أَنَسٍ عَنْ عَبْدِ اللَّهِ بْنِ نَافِعِ بْنِ أَبِي الْعَمْيَاءِ عَنْ الْمُطَّلِبِ بْنِ رَبِيعَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ صَلَاةُ اللَّيْلِ مَثْنَى مَثْنَى وَإِذَا صَلَّى أَحَدُكُمْ فَلْيَتَشَهَّدْ فِي كُلِّ رَكْعَتَيْنِ ثُمَّ لِيُلْحِفْ فِي الْمَسْأَلَةِ ثُمَّ إِذَا دَعَا فَلْيَتَسَاكَنْ وَلْيَتَبَأَّسْ وَلْيَتَضَعَّفْ فَمَنْ لَمْ يَفْعَلْ ذَلِكَ فَذَاكَ الْخِدَاجُ أَوْ كَالْخِدَاجِ.
English Translation
Harun ibn Ma'ruf narrated to us, Ibn Wahb informed me, Yazid ibn Iyad informed us, from Imran ibn Abi Anas, from Abdullah ibn Nafi' ibn Abi al-Amya', from al-Muttalib ibn Rabi'ah, that the Messenger of Allah, peace and blessings be upon him, said: Night prayer is two by two; and when one of you prays, let him recite the tashahhud in every two rak'ahs, then let him be persistent in his request, then when he supplicates let him be still, humble himself, and show his weakness. Whoever does not do that, that is deficiency, or something like deficiency.
