Asr prayer
Shia differs regarding the end of zuhr time. Per all major Jafari jurists, the end of dhuhr time is about 10 minutes before sunset, the time that belongs exclusively to asr prayer. Dhuhr and asr time overlap, apart from the first 5 minutes of dhuhr, which is exclusively delegated for it. Asr prayer cannot be offered before zuhr in the zuhr time.
