From him (Ahmad Ibn Muhammad Ibn Khalid) that he narrated from Al-Jamurani from Al-Hasan Ibn Ali Ibn Abi Hamzah, from Sandal, from Abu al-Sabbah al-Kinani, that Abu Ja'far (al-Baqir) (as) said: "Indeed, Allah (azwj) loves from His believing servants every servant who is persistent in supplication. Therefore, you should engage in supplication during the pre-dawn hours until sunrise, for it is a time when the gates of heaven are opened, provisions are distributed, and great needs are fulfilled."

10. Ali Ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar Ibn ‘Udhaynah that he heard Aba 'Abdillah (al-Sadiq) (as) say: "Indeed, there is an hour in the night during which if a Muslim servant coincides with it in prayer and supplication to Allah (azwj), 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."
