Washing Hands Upto Elbow In Wudu
That is correct, but if you have already washed the hands in the beginning, then you can simply wash the arms later. You can also wash the arms from elbow to fingertips again.
Please refer to the commandment of God, in verse 5:6, and try to understand the message when God is directly talking to us: 5:6 O you who believe, when you observe the Salat, you shall: (1) wash your faces , (2) wash your arms to the elbows , (3) wipe your heads , and (4) wash your feet to the ankles . This is the entire method of wudu. We should appreciate God and be thankful to him that He has revealed easy and clear verses for our guidance, and not complicate things unnecessarily as this counts as ingratitude just like Bani Israel used to do by asking countless questions on simple commandments of God.
