Adding titles of respect like Sayyiduna in Dua, etc.

Q: regarding the word Sayyiduna. i understand this is a title of respect, but should we not stick to the original wordings of the Ahadith when making duaa etc. for example someone may add Sayyiduna, then Moulana. Someone will add Jalle Jalalahu when reading durood after the name of Allah. So someone else will add and add and the original will be distorted. The addition of such words implies that the original wordings are not respectful enough?

Problems in the Middle East

Q: Here in our small Muslim community in U.K. we hear a lot of things happening in the Middle East Syria etc. from people amongst us who went there. Horrible things are being done to our Muslim brothers and sisters there and it is really pitiable. So when does it becomes compulsory upon us to answer the call of these oppressed Muslim brothers and sisters? Will we be sinners if we don’t answer their call?
