Is it compulsory to recite a surah after the Faatiga in fard or sunnah salaah. If one skips the recitation of a surah after the Faatiga is the salaah still valid. Shukran

Wa alaykum salam wa rahmatuLlahi wa barakatuHu,

For one who is able, reciting Surah al-Fatihah is obligatory. And this is the case when one is praying alone, behind an imam, or as the imam. As well, it is the case when the prayer is audible or inaudible, obligatory or supererogatory. And this applies to every rak’ah of prayer except for when one is a latecomer. (Rawdah al-Talibin 1/241)

And Allah knows best.
