وَقَالَ اَلنَّبِيُّ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ فِي وَصِيَّتِهِ لِعَلِيٍّ عَلَيْهِ اَلسَّلاَمُ: «يَا عَلِيُّ عَلَيْكَ بِصَلاَةِ اَللَّيْلِ وَ عَلَيْكَ بِصَلاَةِ اَللَّيْلِ وَ عَلَيْكَ بِصَلاَةِ اَللَّيْلِ.
Hadith.1399 - The Prophet (sw) said in his advice to Imam Ali (as): "O’ Ali, adhere to the night prayer, adhere to the night prayer, adhere to the night prayer”.
وَ رُوِيَ: «أَنَّ مَنْ قَرَأَ فِي اَلرَّكْعَتَيْنِ اَلْأَوَّلَتَيْنِ مِنْ صَلاَةِ اَللَّيْلِ فِي كُلِّ رَكْعَةٍ مِنْهُمَا اَلْحَمْدَ مَرَّةً وَ «قُلْ هُوَ اَللّٰهُ أَحَدٌ» ثَلاَثِينَ مَرَّةً اِنْفَتَلَ وَ لَيْسَ بَيْنَهُ وَ بَيْنَ اَللَّهِ عَزَّ وَ جَلَّ ذَنْبٌ إِلاَّ غَفَرَ لَهُ.

وَ رُوِيَ: «أَنَّ مَنْ قَرَأَ فِي اَلْوَتْرِ بِالْمُعَوِّذَتَيْنِ وَ «قُلْ هُوَ اَللّٰهُ أَحَدٌ» قِيلَ لَهُ أَبْشِرْ يَا عَبْدَ اَللَّهِ فَقَدْ قَبِلَ اَللَّهُ وَتْرَكَ.
Hadith.1401 - It is narrated : "Whoever recites in the Witr prayer the two protective chapters (Surah Al-Falaq and Surah An-Nas) and 'Qul Huwa Allahu Ahad' (Surah Al-Ikhlas), it will be said to him, 'Rejoice, O’ servant of Allah (swt), for Allah (swt) has accepted your Witr.'"
