I haven’t remembered dua mathura. Can I read “Rabbijalni muqimassalati wa min zurriyati rabbana wa taqabbal dua”.

You should read the following dua:
رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ.
In case you do not remember it then you can read the following dua:
رَبِّ اجْعَلْنِي مُقِيمَ الصَّلاَةِ وَمِن ذُرِّيَّتِي رَبَّنَا وَتَقَبَّلْ دُعَاء .
Allah knows Best!
