ANSWER:
Doubting the hadeeth is the first step to rejecting it! Allah stated in the Quran that He will preserve and protect the Thikr which is the Quran and sunnah. He also ordered us to obey Him and the Prophet salla Allahu Alaihi wa Sallam.
Insinuating that the hadeeth is not 100% authentic or accurate opens the door for rejecting all Hadeeths that we don’t like or goes against our desires and this is the way of people of innovation.
Avoid this person as he is a bad news!
