اللّه کے محبوب ﷺ
وَمَآ أَرْسَلْنَـٰكَ إِلَّا رَحْمَةً لِّلْعَـٰلَمِينَ
"And We have not sent you, [O Muḥammad], except as a mercy to the worlds" (Qur'an 21:107)
Prophet (ﷺ) is Rahmah, and his sending is Rahmah, his message is Rahmah, his teachings is Rahmah, and believing and acting upon what he has come with is Rahmah. Therefore, he is everything associated with mercy, that is Rahmat-al-lil-alameen.
