The first rak‘ah includes thana, refuge and basmalah before recitation. Repeating ta‘awwudh and repeating basmalah in later rak‘ahs are not necessarily treated alike.
Hanafi discussions include reciting basmalah at the beginning of each rak‘ah’s al-Fatihah while linking ta‘awwudh more closely to the initial opening. The distinction stems from what each invocation is understood to introduce.
