The Sahabah (radi Allahu anhum) asked Rasul Allah (sal Allahu alaihi wa sallam) about the Dajjal, “O Messenger of Allah, how long will he stay on earth?” He replied, “Forty days; a day like a year, a day like a month, a day like a week, and the rest of the days like your days.” The Sahabah asked, “O Messenger of Allah, on that day which is like a year, will the Salat (prayers) of one day be sufficient for us?” Rasul Allah (sal Allahu alaihi wa sallam) replied, “No. Calculate the time (for prayer).” [Sahih Muslim] the sahaba (rd) asked if the salaat of one day (i.e 5 salaat) will suffice for the day that is like a year. why would they ask that? is it because that day which is like a year will have one sunrise and one sunset but the normal 24 hour period will be elongated into 12 months? and the Prophet replied that it will not suffice. i.e 5 prayers in that day that is like a year will not suffice.....and then instructed the sahaba (rd) to calculate the time for prayer. so if 5 prayers will not suffice in that day which is like a year then that indicates that more than 5 prayers will have to be prayed. which means that the period will definately be longer than 24 hours as there is only 5 prayers in 24 hours but the sahaba (rd) were instructed to pray more than 5. you catch ma drift?
