Mishnah Berurah — משנה ברורה

With alacrity - Not exactly, but rather he should wait a bit and not get up immediately, because it is damaging for the body (Tractate Gittin 70). It is good to say immediately upon rising "I give thanks to You living and everlasting King for You have restored my soul with mercy. Great is Your faithfulness." The word "mercy" should be said with a pause [after it], and "Great is your faithfulness" without a pause. And this is [taken] from the verse "Each morning refreshed...[Great is your faithfulness]" (Lamentations 3:23), that the Holy One Blessed be He upholds his faithfulness to return the souls which were deposited [by Him] in the morning. And there is no need to wash hands [before saying Modeh Ani], even if they are dirty, because in this wording there is no mention of any [Divine] Name or appellation. Nevertheless, it seems it is forbidden to learn Torah before washing hands, and even without that, it is forbidden [to learn] before [reciting] the blessing of the Torah. See further above at the end of se'if katan 2. [And also] se'if 3.
