وَصَدَقَ and he was correct
A fused 'and' plus a past-tense verb with its 'he' subject built in, 'and he spoke truly'. The plural-free 'he' is carried in the verb's shape, opening the affirmation.

And a man continues to tell the truth and to seek truthfulness until he is recorded with God as a truthful person.
يَصْدُقُ he tells the truth
A present-tense verb 'tells the truth' with its 'he' subject inside, describing the ongoing behavior governed by the 'continues' frame. It paints the habitual action that persists.
فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسِلْمِ أَمَّا إِنَّهُ قَدْ صَدَقَكَ وَهُوَ كَذُوبٌ،
The Prophet, may God bless him and grant him peace, said: Know that he has indeed told you the truth, yet he is a liar.
صَدَقَكَ told the truth to you
A past-tense verb of telling-the-truth with the 'you' object built onto its end, so the act, an unstated 'he' doer, and the listener as recipient sit in one word. The attached ending marks the addressee as the one told the truth.
فَعُرِفَ سَيِّدُهُ أَنَّهُ قَدْ صَدَقَ فَطَابَتْ نَفْسُهُ
Then his master realized that he had been truthful, and his soul was pleased.
صَدَقَ been truthful
A past verb, 'was truthful', with the 'he' subject built in, governed by the preceding 'qad' to read as a completed, emphasised 'had indeed been truthful'. The doer sits inside the verb. It is the substance of what the master realised.
قَالَ صَدَقْت
He said: 'You have spoken the truth.'
صَدَقْتَ you have spoken the truth
A past-tense verb 'you spoke truly', addressed to a single male listener; the '-ta' on the end is the built-in 'you' subject, so no separate pronoun appears. It forms a complete one-word sentence confirming the previous speaker. Arabic folds subject person, number and gender into the verb ending like this.
قَالَ صَدَقْت
He said: 'You have spoken the truth.'
صَدَقْتَ you have spoken the truth
A past-tense verb 'you spoke truly', spoken to one male listener; the '-ta' ending is the built-in 'you' subject. It stands as a complete one-word sentence affirming the previous speaker. Person, number and gender of the doer all live inside the verb's ending.
