تَدْرِي know
A present-tense verb with the 'you' subject folded inside it, so no separate pronoun is needed. Arabic builds the doer into the verb through its prefix and shape, which is why one word covers what English splits into 'you' plus 'know'.
فَقَالَ يَا معَاذ أَتَدْرِي مَا حق الله على الْعباد
So he said, 'O Muadh, do you know what is Allah's right upon the servants?'
أَتَدْرِي do you know
This single word packs a question marker, the prefix that turns a statement into a yes-or-no question, onto a present-tense verb that already carries 'you' as its subject. So one Arabic word asks 'do you know', with the questioning, the tense, and the person all built in.
فَإِنْ كُنْتَ لَا تَدْرِي فَتِلْكَ دِيَارُهُمْ
So if you do not know, then those are their homes.
تَدْرِي you know
A present-tense verb of knowing, carrying its 'you' subject inside the form. Negated by the particle before it, it states the condition's content, your not knowing, which the demonstrative answer then resolves by pointing at the graves. No separate 'you' is written.
وَاللَّهِ مَا تَدْرِي يَا اِبْنَ أَخِي
By God, you do not know, O my nephew.
تَدْرِي you know
A present-tense verb, 'know', with the 'you' (singular) subject in its prefix; under the preceding 'not' it reads 'you do not know'. The 'you' doer is carried inside the verb. The negation just before it flips the statement to the negative.
