2. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr from ‘Abd al-Rahman ibn Salim from Ishaq ibn ‘Ammar who has said the following: “I once asked abu ‘Abd Allah عليه السلام, to teach me about the most excellent time for the morning Salah (prayer). He (the Imam) عليه السلام, said, ‘About the coming of dawn, Allah, most Majestic, most Glorious, says, “You must perform Salah (prayer)) and the recitation at dawn. The recitation at dawn certainly was witnessed.” (17:78) It is a reference to the morning Salah (prayer) which is witnessed (attended) by the angels of the night and the angels of the day. When a servant of Allah performs Salah (prayer) at dawn, it is written in his favor twice: once by the angels of the night and once by the angels of the day.’”
