Does Surah Maidah verse 67 suggest that the Prophet (SAW) had initially hesitated to give the most important part of his message? If so, why did the Prophet (SAW) hesitate when he had never faltered before that?
"O Apostle! Communicate that which has been sent down to you from your Lord, and if you do not, you will not have communicated His message, and Allah shall protect you from the people. Indeed Allah does not guide the faithless lot." Qur'an 5:67
The Prophet Muhammad {SAWA) never hesitated to convey any message from Allah (SWT) and the verse 67 in Sura Al-Ma'ida never suggested that. Allah (SWT) wanted the whole Muslims in all times to know the great importance of the order of Allah to the Prophet to declare the divine and legitimate leadership after him being the most important factor of the future of Islam. Many well known persons will not like that announcement because personal enmity against Ali who killed their relatives, that is why, you read that Allah is assuring the Prophet that Allah will protect you from the evil people.
Wassalam.
