Cool, thanks for clarifying. Also in the obligatory 5 prayers is there any place where you can insert personal prayers?
Actually there is.
for example : during sujoods, and sitting between sujoods.
for sitting between two sujoods I normally made personal prayer:
rabighfirlii warhamni wajburni warfa'ni warzuqni wahdini wa'afini
(Oh my lord forgive me and forgive all my sins and mistakes, and give me Your blessings, and cover up all my past sins and mistakes, and raise me/my status in this world and hereafter, and give me good rizq/wealth, and make my deen strong, and give me good health).
There is a hadith that says "Allah is closest to His slaves during prostration"
So I tend to make (by heart) personal prayers during the sujoods after I praised His beautiful attributes "Subhana robbi al a'laa wabihamd".
But as br. Woodrow has explained above, right after we finish fard prayers is amont the most mustahhab (highly recommended) time to make personal prayers. Most muslims I know would use this moment to do just that.
