Sura 28 Al-Qasas (The Stories), ayah 27

1. قَالَ إِنِّي أُرِيدُ أَنْ أُنْكِحَكَ إِحْدَى ابْنَتَيَّ هَاتَيْنِ عَلَىٰ أَنْ تَأْجُرَنِي ثَمَانِيَ حِجَجٍ ۖ فَإِنْ أَتْمَمْتَ عَشْرًا فَمِنْ عِنْدِكَ ۖ وَمَا أُرِيدُ أَنْ أَشُقَّ عَلَيْكَ ۚ سَتَجِدُنِي إِنْ شَاءَ اللَّهُ مِنَ الصَّالِحِينَ

   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 Allah wills, from among the righteous."

   28:27
