62:9 O you who believe! When the call is heard for the salat at congregation time, then proceed to the remembrance of Allah and leave trade.
I made the above amateur translation using other English translations. I have translated 'yawm' as 'time' instead of 'day'. Is this an acceptable translation?
There are 5 times of congregation in a mosque per day. In view of 62:9, do muslims have a duty to do salat in congregation in a mosque 5 times a day?
Yume is true translation but it means A Day. So Jumah is a day for weekly Prayers day and the AZAN tells the Muslims to rush towards Majsid to Pray Salat and after completion of salat disburse in the land for business
