Regarding "Tafseer by Opinion", Nabi SAW said:
"Whoever explained the Quran with one's own opinion, entered Disbelief in Islam."
Ulama wrote that if someone uses one's own wisdom to pickup the meaning without the knowledge of Tafseer, and these meaning were correct also. Yet, this person says that, "In my opinion"... followed by the meaning, yet this person made an error in his speech by pointing the meaning of Tafseer towards oneself.
Who are we, to claim about the holy Tafseer, that "In my Opinion"?
