In fusha .. we can say اسعد الله اوقاتكم ...or اسعد الله صباحكم/مساءكم according to the time of the day ....

In syrian dialect "for example" we can say يسعد صباحكن/مساكن 

By th e way , i think السلام عليكم is the best greeting even if it s an islamic term ... because it means pease be upon u ♡ ...and its a wonderful meaning .. espetially when we lose it ..then we realise how pease is so important 💔

Watch this. It's specifically for Gulf Arabic but quite comprehensive.
