You had mentioned that Rasoolullah S.A.W.S. used to make du’a during Sajda of a Nafl Salaat. Should these du’aas be Qur’aanic or Masnun or simply any du’a in Arabic? Are there any restrictions?

The following are some of the Du'aas recited by Rasulullah (Sallallaahu Alayhi Wasallam) in Ruku:
a) Subhaanakallaahumma wa bihamdika. Allaahumma ighfir liy (Sahih Bukhari and Sahih Muslim)
b) Allaahumma laka raka'atu wa bika aamantu, wa laka aslamtu. Khasha'a laka samee'a wa basaree wa mukkhee wa 'adhmee wa 'asabee. (Sahih Muslim)

The following are a few of the Du'aas recited by Rasulullah (Sallallaahu Alayhi Wasallam) in Sajdah:
a) Same as the first Du'aas mentioned above. (Sahih Bukhari and Sahih Muslim)
b) Allaahumma laka sajadtu wa bika aamantu wa laka aslamtu, Sajada wajhee lilladhiy khalaqahu wa sawarahu, wa shaqqa sam'ahu wa basarahu, tabaarakallaahu ahsanal khaaliqeen. (Sahih Muslim)

c) Allaahumma a'oodhu biridhaaka min sakhaika, wa bimu'aafaatika min 'uqoobatika. Wa a'oodhu bika minka laa uhthee thanaa-an alayka, anta kamaa athnayta 'alaa nafsik. (Sahih Muslim)

For reference of other such Du'aas, refer to al-Azkaar of Imaam Nawawi pgs.76-78 and 81-82
