It was narrated from Ibn ‘Abbas that the Messenger of Allah said: “Whoever tells of a false dream, will be ordered (on the Day of Resurrection) to tie two grains of barley together, and he will be punished for that.”
حَدَّثَنَا بِشْرُ بْنُ هِلاَلٍ الصَّوَّافُ، حَدَّثَنَا عَبْدُ الْوَارِثِ بْنُ سَعِيدٍ، عَنْ أَيُّوبَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ تَحَلَّمَ حُلُمًا كَاذِبًا كُلِّفَ أَنْ يَعْقِدَ بَيْنَ شَعِيرَتَيْنِ وَيُعَذَّبُ عَلَى ذَلِكَ " .
