وَمِنْ آيَاتِهِ أَنْ خَلَقَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَاجًا لِّتَسْكُنُوا إِلَيْهَا وَجَعَلَ بَيْنَكُم مَّوَدَّةً وَرَحْمَةً
Wa min ayatihi an khalaqa lakum min anfusikum azwajan litaskunu ilayha wa ja'ala baynakum mawaddatan wa rahmah
And among His signs is that He created for you from yourselves mates that you may find tranquility in them, and He placed between you affection and mercy.
This verse describes marriage as one of Allah's signs (ayat) — proof of His wisdom and mercy. The three gifts in marriage are sakinah (tranquility), mawaddah (love), and rahmah (mercy). Reciting this verse as a du'a is asking Allah to manifest these three gifts in one's marriage.
