In the last two fard rakahs, reciting al-Fatihah remains the preferable Sunnah. Remaining silent or saying tasbih does not carry the same Hanafi ruling as omitting the recitation required in the first two.
Shafi‘i jurisprudence requires al-Fatihah in every rakah, while the Hanafi distinction separates the first two from the last two. Their reasoning differs on the generality and specification of recitation requirements.
