Discussion on ilm-e-Gayb

My question

Prove Ilm ul Gayb from the Hadees below which is used to quote by the deviants to deny the ilm ul Ghayb of Our Master Sallallahu Alaihi Wasallam

Volume 9, Book 88, Number 174:
Narrated Sahl bin Sa'd:

I heard the Prophet saying, "I am your predecessor at the Lake-Fount (Kauthar), and whoever will come to it, will drink from it, and whoever will drink from it, will never become thirsty after that. There will come to me some people whom I know and they know me, and then a barrier will be set up between me and them." Abu Sa'id Al-Khudri added that the Prophet further said: "I will say those people are from me. It will be said, 'You do not know what changes and new things they did after you.' Then I will say, 'Far removed (from mercy), far removed (from mercy), those who changed (the religion) after me! "

Answer by a Student:
There are many in the hadith which prove the ilm ul gayb..

1. The river of kawther and the fact that they will never be thirsty

2. "Im your predecessor...meaning the Holy Prophet Sallallahu Alaihi Wasallam is aware who will come to the river kawther

3."some people whom I know ..and I will say they re from Me..."shows clearly that the Holy Prophet Sallallahu Alaihi Wasallam knows about the people who came after Him and their actions too..

4. The words.."far removed...indicate that the Holy Prophet Sallallahu Alaihi Wasallam is aware of those who changed the religion and they have already been removed from Allah's mercy..

Wahabis/Salafis/Deobandis do all what they want and the way they want in the name of Islam, they ask for evidences only when the remembrance of The Beloveds of Allah is held

Thus it is evident that they got animosity towards those who are loved by Allah Tha'ala

Dear Muslims brothers and sisters,
Continue your practice and ignore the idiots
