Why are there only 5 remembrances in the 6 remembrances we say after davening?
Answer:
The six remembrances are: Coming forth from Egypt; the event of Har Sinai; the striking of Miriam after she spoke against Moshe; the deeds of Amalek; the sojourns and the troubles of our ancestors in the wilderness; the Sabbath. All of these are mentioned in the siddur at the end of the Shacharis prayer service.
