For example, if Dhuhr prayer starts at 11:30am and ends at Asr prayer 3:00pm, so the time frame for Dhuhr prayer is 3 hours and a half. Some people say that offering Dhuhr prayer earlier in this time frame is better than offering it in the middle or near the end of the time frame. Some other people say it's ok to offer the prayer any time during the time frame because the rewards will be the same as offering it earlier.
So my question is, which is true?
I usually pray Dhuhr in the middle of the time frame (around 1:45pm).
