Qur'an 28:27

قَالَ إِنِّىٓ أُرِيدُ أَنْ أُنكِحَكَ إِحْدَى ٱبْنَتَىَّ هَـٰتَيْنِ عَلَىٰٓ أَن تَأْجُرَنِى ثَمَـٰنِىَ حِجَجٍ ۖ فَإِنْ أَتْمَمْتَ عَشْرًا فَمِنْ عِندِكَ ۖ وَمَآ أُرِيدُ أَنْ أَشُقَّ عَلَيْكَ ۚ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ مِنَ ٱلصَّـٰلِحِينَ

“He said, "Indeed, I wish to wed you one of these, my two daughters, on [the condition] that you serve me for eight years; but if you complete ten, it will be [as a favor] from you. And I do not wish to put you in difficulty. You will find me, if Allāh wills, from among the righteous."”
