Being mentioned in sunni books doesn't make it Sahi. Those are weak ahadeeth. Imam Ahmed included those in his book of Ilal(i.e book of hidden defects). Whereas on the other hand shias called it sahi.

Secondly I would like to see that whether those (weaK) hadeeth in our books are from Israiliyat or those are marfu hadeeth.

Feel free to read up on what Ibn Katheer, al-Tabari, al-Tabarani and others have narrated on this issue. The point is not whether they are authentic or not. But the fact that some people make fun of things just because it happens to be in Rafidi books and sounds strange to them, and at times it may be that he has made fun of something that was partially accepted, or accepted by some authorities from Ahl al-Sunnah. Ridiculing it then becomes disrespectful towards those authorities. It is one thing to be interested in conducting research, another to overstep ones boundaries in ridiculing hadiths when one is not trained in the Ulum of Hadith. The same goes for issues of Fiqh etc.
