BAYHAQI 2479:
from Abū ʿAbdullāh al-Ṣunābiḥī —
[Machine] He arrived in the city during the caliphate of Abu Bakr al-Siddiq, and he prayed behind Abu Bakr al-Maghrib. Abu Bakr recited in the first two units of prayer from the mother of the Quran and a surah from the shorter, detailed ones. Then he stood for the third unit of prayer and I approached him until my clothes almost touched his clothes. I heard him recite from the mother of the Quran and this verse: "Our Lord, let not our hearts deviate after You have guided us and grant us from Yourself mercy. Indeed, You are the Bestower" [Al-Imran 8]. Abu Sa'id added in his narration, Shafi'i said and Sufyan ibn 'Uyaynah said, when 'Umar ibn Abd al-Aziz heard this from Abu Bakr al-Siddiq, he said, "If I hadn't heard this before, I would have taken it."
