It is narrated from Fudayl bin Iyad (may Allah have mercy on him) that he said: "Between Yusuf (peace be upon him) being separated from the lap (care) of his father Ya'qub (peace be upon him) and their meeting again, there was a period of eighty (80) years."

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: "Yusuf (peace be upon him) was bought for only twenty dirhams. At the time he sent word from Egypt to his family (to summon them), they numbered three hundred and ninety (390). Their men were prophets and their women were truthful (siddiqat). And by Allah! When they departed (from Egypt) with Musa (peace be upon him), their number had reached six hundred and seventy thousand." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
