In between the Adhan & Iqamah one may make one sijdah, sit & recite recite this dua :
Oh Allah make my heart gentle, my life prosperous, and give me continued sustenance,
and fix for me a place near the grave of your Messenger Muhammad (May the prayers & salutations of Allah be on him & his family) a place of stay & rest (grant me all of this)
& ask for ones wishes as wishes sought between Adhan & iqamah are not rejected.
