No of ayats one has to read in namaz

After reciting Surah Fatiha you have to recite at least three Ayats. But remember in each Rakaat you have to recite different Ayats after reciting Surah Fatiha and they should be in proper sequence, number wise. For example

In First Rakaat after Reciting Surah Fatiha you can Recite Al-Kafirun (No. of Surah #109)

In Second Rakaat after Reciting Surah Fatiha you can Recite Al-'Ikhlas (No. of Surah #112)

In Third Rakaat after Reciting Surah Fatiha you can Recite Al-Falaq (No. of Surah #113)

In Fourth Rakaat after Reciting Surah Fatiha you can Recite An-Nas (No. of Surah #114)

Brother believer!..m confused with your answer...why did u give a sequence..i mean cant I just recite sureh ikhlas in first rakat..then sureh kafiroon in second rakaat..then sureh masadd and finally sureh nasr...or in other way/sequence according to my will??

Thanku so much..!
