Hekayat 30 from Chapter 8 of Golestan of Saadi

Everyone sees their own intellect as perfect and their own child as beautiful.

A Jew and a Muslim were arguing

To the point that their conversation made me laugh

In frustration, the Muslim said: If this deed of mine

Is not valid, God, may you end the life of the Jew

The Jew said: I swear by the Torah!

And if I am wrong, I will become a Muslim like you

If all intellect were removed from the face of the earth

No one would suspect themselves to be ignorant.

همه کس را عقل خود بکمال نماید و فرزند خود بجمال.

یکی یهود و مسلمان نزاع می‌کردند

چنان که خنده گرفت از حدیث ایشانم

به طیره گفت مسلمان: گر این قبالهٔ من

درست نیست خدایا یهود میرانم

یهود گفت: به تورات می‌خورم سوگند!

وگر خلاف کنم همچو تو مسلمانم

گر از بسیط زمین عقل مُنعَدِم گردد

به خود گمان نبَرَد هیچکس که نادانم
