Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم will not give benefit without faith. There   are many non-Muslims who have great reverence for the Beloved Prophet    صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم and write books and lecture in reply to the objections made by other non-Muslims, but since they have not embraced Islam, so their replying to the objections will not benefit them as it is an apparent reverence. If such a person held true greatness for the Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم in his heart, he must embrace Islam. Unless there is no true reverence for the Prophet of Rahmah صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, no matter if one spends his entire life worshipping Allah عَزَّوَجَلَّ, all will be useless and will not be acceptable at all before Allah عَزَّوَجَلَّ, about such people Allah عَزَّوَجَلَّ has stated:

وَ  قَدِ مۡنَاۤ   اِلٰی   مَا  عَمِلُوۡ ا   مِنۡ   عَمَلٍ      فَجَعَلۡنٰہُ    ہَبَآ ءً    مَّنۡثُوۡ رًا   ﴿۲۳﴾

Translation from Kanz-ul-Iman: And We turned all the deeds they had performed into scattered floating specks of dust.

 (Part 19, Surah Al-Furqan, verse 23)

And Allah عَزَّوَجَلَّ has also said:

عَامِلَۃٌ    نَّاصِبَۃٌ    ۙ﴿۳﴾     تَصۡلٰی   نَا رًا   حَامِیَۃً    ۙ﴿۴﴾

Translation from Kanz-ul-Iman: Labouring, striving hard. (Yet) Going into the blazing fire. (Part 30, Surah Al-Ghaashiyah, verse 3, 4)

i.e. act upon it, take pains and what would be the return? The same that they will go to the blazing fire. (Fatawa Razawiyyah, vol. 30, pp. 307)

آج لے اُن کی پناہ آج مدد مانگ اُن سے       پھر نہ مانیں گےقیامت میں اگرمان گیا

Dear Islamic brothers! From the abovementioned blessed verses and the blessed sayings of A’la Hadrat رَحْمَةُ اللهِ تَعَالٰی عَلَيْه it has become obvious that reverence for Beloved Mustafa صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم is the real faith. If a person
