Modeh Ani is the first prayer that one traditionally says when awakening in the morning. It thanks God for returning one’s soul after having entrusted the soul to God at night.
The full text reads as follows:
מוֹדֶה אֲנִי לְפָנֶיךָ מלך חַי וְקַיָּם שֶהֶחֱזַרְתָּ בִּי נִשְׁמָתִי בְחֶמְלָה, רַבָּה אֱמוּנָתֶךָ
Modeh ani l’fanecha, melech chai v’kayam, shehechezarta bi nishmati, b’chemla raba emunatecha
