The Holy Prophet (Sallallahu alaihi wa sallam) had a full mouth. He (Sallallahu alaihi wa sallam) had a beautiful voice. His voice had the miraculous quality that whenever He gave a sermon, even the women in the houses would hear it. When He (Sallallahu alaihi wa sallam) gave the sermon in Mina, apart from the 1 lakh plus Sahabah, the inhabitants of Makkah also heard it. Once during a sermon, He (Sallallahu alaihi wa sallam) said, “Sit down” Hadhrat Abdullah bin Rawaha who was with the tribe of Bani Ghanam also sat down. When the Holy Prophet (Sallallahu alaihi wa sallam) spoke, a radiance would issue from His teeth. Hadhrat Abdullah bin Abbas (May Allah be well pleased with them) says that the Holy Prophet’s (Sallallahu alaihi wa sallam) teeth are well spaced. Whenever He (Sallallahu alaihi wa sallam) spoke a radiance could be seen between His teeth.
The words of the Holy Prophet (Sallallahu alaihi wa sallam) are endorsed by Allah SWT with the words:
“Nor does he say (aught) of (his own) Desire. (3)” Surah Najm (53:03)
The Prophet’s (Sallallahu alaihi wa sallam) speech was eloquent and sweet. His speech was very pleasing and would stir the very depths of the heart. His eloquence was such that none could match it. Hadhrat Abu Bakr Siddiq (May Allah be well pleased with him) narrates that he went to the presence of the Holy Prophet (Sallallahu alaihi wa sallam) and said: O Prophet of Allah (Sallallahu alaihi wa sallam), I have toured the entire Arabian peninsula. I have heard the poets of Arabia but I have never heard anybody as eloquent as You. The Holy Prophet (Sallallahu alaihi wa sallam) said, My Lord i.e. Allah SWT taught Me and brought Me up and how well has He taught Me.
