10. Ali Ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar Ibn ‘Udhaynah that he heard Aba 'Abdillah (al-Sadiq) عليه السلام say: "Indeed, there is an hour in the night during which if a Muslim servant coincides with it in prayer and supplication to Allah عز وجل, his supplication will be answered. This happens every night." I asked, "May Allah improve your condition, which hour of the night is it?". He said, "When half of the night has passed, it is the first sixth of the second half of the night."
