Quran 12:10

قَالَ قَآٮِٕلٌ۬ مِّنۡہُمۡ لَا تَقۡتُلُواْ يُوسُفَ وَأَلۡقُوهُ فِى غَيَـٰبَتِ ٱلۡجُبِّ يَلۡتَقِطۡهُ بَعۡضُ ٱلسَّيَّارَةِ إِن كُنتُمۡ فَـٰعِلِينَ ١٠

One of them said, "Do not kill Joseph; let us throw him into the abyss of the well. Perhaps some caravan can pick him up, if this is what you decide to do."
