We said, “Allah’s Messenger, how long would he stay on the earth?” He (ﷺ) said, “For forty days, one day like a year and one day like a month and one day like a week and the rest of the days would be like your days.” We said, “Allah’s Messenger, would one day’s prayer suffice for the prayers of day equal to one year?” Thereupon he (ﷺ) said, “No, but you must make an estimate of time (and then observe prayer).”
I appreciate you providing a source instead of telling the other commenter to find it themselves. You didn’t have to, but you did anyway, and I think in this day and age that’s very respectable.

This doesn’t prove Islam is fake or real, but we should approach subjects we aren’t familiar with with a touch more humility.
Edit: worth noting that fasting runs off prayer times. Can’t have food/drink/sex between the first and fourth prayer.
