Mehta Kalu (Guru Nanak Dev Ji’s worldly father) noticed that as Guru Ji grew older, his quietness increased, and thus took him to a Muslim priest to learn Persian (official language of the time).
According to Gur Balam Sakhiya:
"The Muslim priest, out of consideration for the son of an official, respectfully asked him to sit and asked him sit and he wrote thirty alphabets of Persian on a writing board. The child read those as if he already knew them. He had shown mastery of the language from the start. Then later, he started bunking and remained serious, missing school a lot. The priest said "O Nanak, you don’t study as diligently as you used to. I don’t know how much you study at home…
Nanak said “I have already read and done everything” He gave the Muslim priest his paper.
On the paper were written all the Persian alphabets and against every alphabet there was a stanza written in praise of the Lord. On seeing the paper, the Muslim priest fell at the child Guru’s feet and said: You are a prophet. You have gained all the knowledge without being taught.
