Bayhaqi 3144 — The supplication of qunut

Sa'id bin Abd al-Rahman bin Abza narrates from his father (may Allah be pleased with him) that he said: I prayed the morning prayer behind Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), and I heard him reciting after the recitation and before the bowing: 'Allahumma iyyaka na'budu wa laka nusalli wa nasjudu wa ilayka nas'a wa nahfid, narju rahmataka wa nakhsha 'adhabak, inna 'adhabaka bil-kafirina mulhiq; Allahumma inna nasta'inuka wa nastaghfiruka wa nuthni 'alayka al-khayr, wa la nakfuruk, wa nu'minu bika wa nakhda'u laka wa nakhla'u man yakfuruk' "O Allah, You alone we worship, for You alone we pray and prostrate, and towards You alone we hasten and strive. We hope for Your mercy and we fear Your punishment. Indeed, Your punishment is to overtake the disbelievers. O Allah, from You alone we seek help and from You alone we ask forgiveness; we praise You with good, we do not disbelieve in You, we believe in You, we submit to You, and we disown whoever disbelieves in You." That is how he said it: before the bowing.
Even though its chain is sahih (authentic), those who narrated from Umar (may Allah be pleased with him) that his qunut was after the bowing are more numerous: Abu Rafi', Ubayd bin Umayr, Abu Uthman al-Nahdi and Zayd bin Wahb narrated it, and a number of narrators is more likely to have preserved it accurately than a single one. The excellent way Ubayd bin Umayr presented the hadith indicates his accurate memory and the accurate memory of those who preserved it from him. And it was narrated to us from Sayyiduna Ali (may Allah be pleased with him) that he recited the qunut in the Fajr prayer and made this supplication: 'Allahumma inna nasta'inuka wa nastaghfiruk' "O Allah, from You alone we seek help and from You alone we ask forgiveness."
And it was narrated to us from Abu Amr bin al-Ala' that he used to recite in the supplication of the qunut: 'Inna 'adhabaka bil-kuffari mulhiq' "Indeed, Your punishment is to overtake the disbelievers", meaning with a kasrah on the letter ha (mulhiq).
