رَزَقَنِيَ اللَّهُ لِقَاءَكَ
May God grant me a meeting with you (literally, “God has granted me a meeting with you”).
When said before the meeting, the past tense conveys hope presented as if already realised. The speaker gives a desired outcome the form of an accomplished event.
The interpretation depends on the context showing that the meeting has not yet occurred. Without that clue, a past-tense statement remains an ordinary past assertion.
