Chapter on the Prayer Times (Mawaqit)

Muhammad ibn Yahya narrated from Muhammad ibn Al-Husayn from Uthman ibn Isa from Sama'ah who said: I asked Imam عليه السلام about praying during the night and day when neither the sun nor the moon nor the stars are visible. Imam عليه السلام said: “Exert your judgment and face the qiblah as best as you can.”
