[Other] Salam, Namaste, Unakam and Sasriyakant

Yes, they use asalaam alaikum.
Wa aleike asalaam is a response for asalaam alaikum . wa means and in Arabic, So it's like saying ( and peace be upon you too)
I have some friends who speak farsi and Urdo. I can understand a few words when they speak Farsi but I cannot understand a thing when they speak Urdo.
So i guess Farsi has more common words with Arabic than Urdo. The Urdo script has more letters than Arabic and some letters that look like Arabic are pronounced differently. (I can read Farsi very well, but I can't really read Urdo)
Good Luck in learning Urdo. It's an interesting language.
