Surah Yusuf (Joseph), Verse 62

وَقَالَ لِفِتْیٰنِهِ اجْعَلُوْا بِضَاعَتَهُمْ فِیْ رِحَالِهِمْ لَعَلَّهُمْ یَعْرِفُوْنَهَاۤ اِذَا انْقَلَبُوْۤا اِلٰۤی اَهْلِهِمْ لَعَلَّهُمْ یَرْجِعُوْنَ ۟

Wa qaala lifityaanihij 'aloo bidaa'atahum fee rihaalihim la'allahum ya'rifoonahaaa izan qalabooo ilaaa ahlihim la'allahum yarji'oon

“And (Joseph) told his servants to put their stock-in-trade (with which they had bartered) into their saddle-bags, so they should know it only when they returned to their people, in order that they might come back.”
