The Supplication of Qunoot in Witr Prayer
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 72
وَ رُوِيَ عَنْ سَعِيدٍ اَلْأَعْرَجِ أَنَّهُ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ جُعِلْتُ فِدَاكَ إِنِّي أَكُونُ فِي اَلْوَتْرِ وَ أَكُونُ قَدْ نَوَيْتُ اَلصَّوْمَ وَ أَكُونُ فِي اَلدُّعَاءِ وَ أَخَافُ اَلْفَجْرَ وَ أَكْرَهُ أَنْ أَقْطَعَ عَلَى نَفْسِي اَلدُّعَاءَ وَ أَشْرَبَ اَلْمَاءَ وَ تَكُونُ اَلْقُلَّةُ أَمَامِي قَالَ فَقَالَ لِي «فَاخْطُ إِلَيْهَا اَلْخُطْوَةَ وَ اَلْخُطْوَتَيْنِ وَ اَلثَّلاَثَ وَ اِشْرَبْ وَ اِرْجِعْ إِلَى مَكَانِكَ وَ لاَ تَقْطَعْ عَلَى نَفْسِكَ اَلدُّعَاءَ.
It is narrated from Sa'id al-A'raj that He said: I said to Imam Jafar ibn Muhammad Al-Sadiq عليه السلام "May I be your ransom, sometimes I am in the Witr prayer and have already intended to fast. I am engaged in supplication and I fear the approach of dawn, but I dislike interrupting my supplication to drink water, and there is a water jug in front of me." Imam عليه السلام said to me: "Take a step, two, or three towards it, drink, and then return to your place without interrupting your supplication."
