7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah ibn Mehran who has said the following: “I once asked abu ‘Abd Allah , about the case of two men who both look toward dawn and one of them say, ‘There is dawn/ but the other one says, ‘I do not see anything/ He (the Imam) said, ‘The one who does not see any dawn, eats but eating is unlawful for one who thinks he has seen the dawn. Allah, most Majestic, most Glorious, says, ‘Eat and drink until the white thread appears from the dark thread of dawn/ (2:187)”
