Can someone answer my question about prayer ?

Assalamu alaikum Whwn I am praying I read surah al fatihah on each raka'at plus another short surah for the first and second raka'at such as surah 103 al asr,surah 105 al fil,surah 106 quraisy surah 107 al ma'un,surah 108 al kausar,surah 109 al kafirun,surah 110 an nasr surah 111 al lahab,surah 112 al ikhlas,surah 113 al falaq and surah 114 an nas. You do not doing wrong although you read just only the same surah,because reading a surah after al fatihah is sunnah and do not mandatory.Your prayer insya allah will be accepted by Allah.
