﴿ وَمَا كُنتَ تَرْجُوٓا۟ أَن يُلْقَىٰٓ إِلَيْكَ ٱلْكِتَٰبُ إِلَّا رَحْمَةًۭ مِّن رَّبِّكَ ۖ فَلَا تَكُونَنَّ ظَهِيرًۭا لِّلْكَٰفِرِينَ ﴾

“Now [as for thyself, O believer,] thou couldst never foresee that this divine writ would [one day] be offered to thee: but [it did come to thee] by thy Sustainer’s grace. Hence, never uphold those who deny the truth [of divine guidance],”

The Prophet’s cause is in every way God’s cause. Prophethood is voluntarily given to him by God without any request on his part. Throughout his entire existence he remains steadfast in adhering to the Truth. He is appointed to announce the plain, unvarnished Truth, even if it is unpleasant to people. He is destined to reach his appointed goal and no impediment shall bar his path. After the Prophet, the same will hold true for those who rise, in conformity with the Prophet, as missionaries of Truth. To the extent that they resemble the Prophet in conduct, they will go on being entitled to succour promised by God to His prophets in His Book.
