- It is required to daven al hanissim (according to many, more correctly–v’al hanissim) from a siddur, not by heart, as one is not used to saying it.
- Whenever hallel shalem is said, care must be taken to say every single word, and to pronounce every word correctly, or one is running the risk of a beracha l’vatala (and also one would not be yotzei).
- Although it is definitely preferable to say Hallel right after shemoneh essray; but if it were not said, one could and should say it the entire day, until sunset.
- If one forgot to say al hanissim (or v’al hanissim) in bentching in the middle of the second berachah, and the conclusion of the berachah has already been said, one should continue bentching, and upon reaching the special harachaman prayer which is said on Shabbos or Yom Tov, one says: “harachaman hu ya’aseh lanu nissim v’nifla’os keshaim she’assah la’avoseinu bayamim haheim bazeman hazeh……Biyemei…..
The yevanim didn’t destroy the Beis HaMikdash….they “only” defiled it. And it is quite instructive that they did not simply spill out all oils–they desecrated them.

Is it that different to disgrace and dishonor its kedushah?
