Salaatul Ayat (Short Version)

Make the intention [of performing the prayer], than say the Takbir and recite Sūrah al-Fatihah; 

Then, divide the verses of the other (second) surah into five parts and recite one verse or more, or even less, provided that (based on obligatory precaution) it is a complete sentence. 

You must start from the beginning of the surah and must not suffice with reciting bismillāh [on its own and count that as one verse]. Then, go into rukoo, raise your head, and without reciting Sūrah al-Fatihah (again) recites the second part of the other surah. Then go into rukoo again, and so on until you complete the other surah before you go into the fifth rukoo.

For example, if the other surah is Sūrat al-Falaq, first say:

بِسْمِ اللّٰهِ الرَّحْمٰنِ الرَّحِيمِ‏. قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ

“bismil lāhir raḥmānir raḥīm. qul aʿūdhu birabbil falaq”

“In the Name of Allah, the All-Beneficent, the Ever-Merciful. Say, ‘I seek the protection of the Lord of the daybreak.”

and go into rukoo [for the first time]; then stands up and say:

مِنْ شَرِّ مَا خـَـلَقَ

“min sharri mā khalaq”

“from the evil of what He has created,”

and go into rukoo again [for the second time]; then stands up and say:

وَ مِنْ شَرِّ غَاسِقٍ إِذَا وَقَبَ

“wa min sharri ghāsiqin idhā waqab”

“and from the evil of the dark night when it settles,”

and go into rukoo again [for the third time]; then stands up and say:

وَ مِنْ شَرِّ النَّـفَّاثَاتِ فِي الْعُقَدِ

“wa min sharrin naffāthāti fil ʿuqad”

“and from the evil of the witches who blow on knots,”

and go into rukoo again [for the fourth time]; then stands up and say:

وَ مِنْ شَرِّ حَاسِدٍ إِذَا حَسَدَ

“wa min sharri ḥāsidin idhā ḥasad”

“and from the evil of the envious one when he envies.”

and go into rukoo for the fifth time. 

Then stands up, performs two sajdahs, and then proceeds to perform the second rakʿah in the same way as the first.

And after the second sajdah [of the second rakʿah], recite the tashahhud and the salām of the prayer.
