In Ayah 107 of Surah Al-Anbiya, Allah (SWT) said:

“And God has not sent you (O’ the Prophet Mohammad (PBUH)) except as a mercy to the worlds.” It is understood from this Ayah that the Prophet of Islam (PBUH) is the manifestation of all the Divine Mercy. Therefore, the Divine Mercy and the Divine Compassion, as well as mercy for this world and compassion for the hereafter, and any other sort of kindness are especially just for the Prophet of Islam (PBUH). The Prophet (PBUH) is not only a mercy to all the human beings but he is also a mercy for all Jinns and even other creatures of Allah (SWT).
