Allah said in the Holy Quraan “O You Who Believe, when the call is made for prayer on Friday, then hasten to remember Allah and leave your trade…”. Muhammed (PBUH) strongly encouraged muslims to arrive early to Friday prayer. The earlier you become the bigger your reward from Allah is. Once Imam climbs the pulpit, no additional reward is granted. ““The one who comes early to the Jumu`ah prayer is like one who sacrifices a camel, then [i.e. coming later than that is] like one who sacrifices a cow, then like one who sacrifices a sheep, then like one who sacrifices a duck, then like one who sacrifices a chicken, then like one who sacrifices an egg.”
Inshaa’ Allah, Fajr is at 6:50 and Isha is at 7:45.
