25. This sentence is connected with the theme preceding the parenthetical clause like this. Some people will say: “They were three and the fourth was their dog...”, and some people will say that they remained in the cave for three hundred years and some others would add nine more years (to the reckoning of the period). We are of the opinion that the number of the years, 300 or 309, has not been stated by Allah Himself but Allah has cited these as sayings of the people. This opinion is based on this succeeding sentence: Allah knows best about the period of their stay there. If the number of years, given in (Ayat 25), had been from Allah, this succeeding sentence would have been meaningless. Abdullah bin Abbas has also opined that this is not the saying of Allah but that of the people which has been cited as a part of the story.
