وَلَبِثُوا۟ فِى كَهْفِهِمْ ثَلَٰثَ مِا۟ئَةٍ سِنِينَ وَٱزْدَادُوا۟ تِسْعًا
<p>As for the period of sleep in the Cave given as three hundred nine years in the third verse (27), this statement concerning the time duration, as evident from the sequential arrangement of the Qur’ an, is but from Allah Ta’ ala. Ibn Kathir has declared this to be the position of the majority of commentators, earlier and later. Abu Hayyan and al-Qurtubi have also adopted this view. But, they have also reported another saying from Qatadah and others. It holds that this statement of three hundred nine years is also the saying of some of those who had differed and that the saying of Allah was what was said later: اللَّـهُ أَعْلَمُ بِمَا لَبِثُوا (Allah knows best how long they stayed - 26). The reason is, had the earlier statement giving the duration as three hundred nine years been the word of Allah, there would have been no occasion for saying: اللَّـهُ أَعْلَمُ بِمَا لَبِثُوا (Allah knows best how long they stayed) after that. But, the majority of commentators have said that both these sentences are the word of Allah. The first one describes reality as it is. The second one warns those who differ with it. They have been told that once the statement giving the duration has come from Allah, accepting it is mandatory. Since He is the One who really knows, trying to differ with Him on the basis of mere conjectures and opinions is (to make an understatement) unreasonable. The question that arises here is about the manner in which the Holy Qur'an has described the duration of stay. First it mentions three hundred years. After that, it has said that added to those three hundred there are nine. The number three hundred nine was not given initially. According to commentators, there is a reason for it. Since the Jews and Christians followed the Solar Calendar, their count remained three hundred years. And since Islam goes by the Lunar Calendar in which three more years are added every hundred years, therefore, three hundred years of Solar Calendar become nine more years in accordance with the Lunar Calendar. It was to tell the difference between the two years that this expressive diction was employed.</p>
