I have heard a speech from Muhammad, which resembles neither the speech of humans nor that of the fairies.” وَ إِنَّ لَهُ لَحَلاَوَةً وَ إِنَّ عَلَيْهِ لَطَلاَوَةً وَ إِنَّ أَعْلاَهُ لَمُثْمِرٌ وَ إِنَّ أَسْفَلَهُ لَمُغْدِقٌ وَ إِنَّهُ لَيَعْلُو وَ لاَ يُعْلَى‏. “His speech possesses a special sweetness and an exceptional beauty. The top of it (like the fruitful branches of a tree) is full of fruits and the bottom of it is (like the roots of an ancient tree) firm and strong.
