وَلَقَدْ جَآءَكُمْ يُوسُفُ مِن قَبْلُ بِٱلْبَيِّنَٰتِ فَمَا زِلْتُمْ فِى شَكٍّۢ مِّمَّا جَآءَكُم بِهِۦ ۖ حَتَّىٰٓ إِذَا هَلَكَ قُلْتُمْ لَن يَبْعَثَ ٱللَّهُ مِنۢ بَعْدِهِۦ رَسُولًۭا ۚ كَذَٰلِكَ يُضِلُّ ٱللَّهُ مَنْ هُوَ مُسْرِفٌۭ مُّرْتَابٌ
And verily Joseph brought you of old clear proofs, yet ye ceased not to be in doubt concerning what he brought you till, when he died, ye said: Allah will not send any messenger after him. Thus Allah deceiveth him who is a prodigal, a doubter.
