Read and reflect on verse 1614 from Surah Yusuf: and they produced his tunic with false blood upon it. [But Jacob] exclaimed: "Nay, but it is your [own] minds that have made [so terrible] a happening...
وَجَاءُوا عَلَىٰ قَمِيصِهِ بِدَمٍ كَذِبٍ ۚ قَالَ بَلْ سَوَّلَتْ لَكُمْ أَنْفُسُكُمْ أَمْرًا ۖ فَصَبْرٌ جَمِيلٌ ۖ وَاللَّهُ الْمُسْتَعَانُ عَلَىٰ مَا تَصِفُونَ
and they produced his tunic with false blood upon it. [But Jacob] exclaimed: "Nay, but it is your [own] minds that have made [so terrible] a happening seem a matter of little account to you! But [as for myself,] patience in adversity is most goodly [in the sight of God]; and it is to God [alone] that I pray to give me strength to bear the misfortune which you have described to me."
