Salam aleykom,
I have heard that an Islamic weekday starts after 3isha prayer. Is this true?
For instance that "khemiis"/Thursday starts after 3isha prayer on Wednesday. Is this correct?
If there's a 3amal that needs to be done a certain weekday, can you do it after 3isha prayer the previous day? Will you get the promised reward then or do you need to wait till the day after and do it during the day?
