Hekayat 8 from Chapter 7 of Golestan of Saadi

I saw a Bedouin telling his son, "O my son, on the Day of Judgment, you will be asked what deeds you have earned, not to whom you are related." Meaning, they will ask you about your actions, not about who your father was.

The cloth of the Kaaba, which people kiss,
Did not gain honor by being spun from silk alone.
It spent a few days in the company of the noble,
And thus, it too became esteemed.

اعرابیی را دیدم که پسر را همی‌گفت یا بُنَّی اِنَّک مسئولٌ یومَ القیامةِ ماذا اکتَسَبتَ و لا یُقالُ بمن انتسبتَ. یعنی تو را خواهند پرسید که عملت چیست نگویند پدرت کیست.

جامه کعبه را که می بوسند

او نه از کرم پیله نامی شد

با عزیزی نشست روزی چند

لاجرم همچنو گرامی شد
