Cf. Siddur, p. 6ff.

The prayers (including Modeh Ani and the morning blessings, etc.) are recited according to the text formulated by the Alter Rebbe, which is known as Nussach HaAri.”1

One whose custom it is to pray according to Nussach HaAri does so even when praying in a congregation whose text is otherwise. This ruling does not counter the injunction, לא תתגדדו — “You shall not separate yourselves.”2

It is permitted to change one’s prayer rite from Ashkenaz or Sephard to Nussach HaAri, provided that the transfer is permanent.3

While one recites the blessing after washing and drying one’s hands in the morning, they are held apart at the height of the peyos.4

One recites all the morning blessings as printed even if they do not apply to him, e.g., if he was awake the whole night and did not change his clothes, provided it is after daybreak. If, however, one slept during the night, he may recite them as soon as he rises, provided it is after midnight.5
