Wa alaikumsalam wa rahmatullaahi wa barakatuhu,

There is no adhan for rawatib sunnah. You pray it like any other prayer and you may read whatever you wish in it.

Asalamu Alaikum Warahmatulah Wabarakatuhu. I just wanted to know how is da 12rakat sunnah nafilahs prayed? What ar da surahs you should recite and dat do you need to do da azaan before doing da prayer. Jazaka Allahu Khair.
