اللَّهُمَّ ارْزُقْنِي زَوْجًا صَالِحًا يُعِينُنِي عَلَى أَمْرِ دُنْيَايَ وَآخِرَتِي
Allahumma-rzuqni zawjan salihan yu'inuni 'ala amri dunyaya wa akhirati
O Allah, provide me with a righteous spouse who helps me in matters of my worldly life and my Hereafter.
The du'a is gender-neutral ("zawjan" can mean spouse of either gender) and the criterion is clear: someone who helps you in BOTH worlds. Not just a partner for dunya — mortgages, dinners, vacations — but for akhirah: waking you for Fajr, encouraging your Quran, softening your heart. The best spouse is not the most attractive or wealthy but the one who makes your Hereafter better.
