Salam brother,
welcome to the LI family, i hope u have a beneficial stay inshallah :)
explore the forums, take part in the discussions and do enjoy!
Regarding ur question.. i think it is permissable to use verses from the quran in du'as. For example.. i once asked for du'as for success and peace of mind, and a brother gave me the following:
Rabbana 'atina mil-ladunka Rahmataw wa hayya lana min amrina rashada
"Our Lord! Bestow on us Mercy from Thyself, and dispose of our affair for us in the right way!"
[18:10]
Rabbana atina fid-dunya hasanatan wa fil 'akhirati hasanatan waqina 'adhaban-nar
"Our Lord! Grant us good in this world and good in the hereafter, and save us from the chastisement of the fire"
[2:201]
As you can see, they are both quoted from the Holy quran, so i guess it is allowed.. and i suppose you say this in the same way you make dua
Some knowlegable people on this may be of more help.. i only know a limited amount. Sorry.. but hope it helps nonetheless... :)
