Day by day I am trying to get closer to Allah and I have started reading books on spirituality and irfan. Their are many rules, views and points to observe to obtain irfan, which I am aware of it. In a book which I forgot the name it says that reciting surah al-anbiya verse 87-88 in sajdah are very good and by now I have memorized this verses but the question is should I recite this verses in every sajdah or in the last sajda of last rakat?

The above verse should be recited in the last Sajda of every salat.
