فَأَوْحَيْنَا إِلَيْهِ أَنِ اصْنَعِ الْفُلْكَ بِأَعْيُنِنَا وَوَحْيِنَا فَإِذَا جَاءَ أَمْرُنَا وَفَارَ التَّنُّورُ ۙ فَاسْلُكْ فِيهَا مِن كُلٍّ زَوْجَيْنِ اثْنَيْنِ وَأَهْلَكَ إِلَّا مَن سَبَقَ عَلَيْهِ الْقَوْلُ مِنْهُمْ ۖ وَلَا تُخَاطِبْنِي فِي الَّذِينَ ظَلَمُوا ۖ إِنَّهُم مُّغْرَقُونَ (27)
(23:27) At this, We revealed to him: Build an ark under Our supervision, according to Our instructions. Then, when Our Command comes and "at-Tannur" *29 begins to boil up, take aboard a pair of every species of animals, and also the members of your own family except those against whom the judgement has already been passed; and do not plead with Me for the workers of iniquity, for they are doomed to be drowned.
*29) Some commentators think that tanner means the earth; others take it for the highest part of the earth; and still others think that the words far-at-tannur in the Text have been used for the break of Dawn. There are some who express the opinion that the words have been used metaphorically for the creation of turmoil. But in view of the context, we see no reason why one should take a farfetched figurative meaning of a clear word of the Qur'an. It appears that a particular oven (tannur) had been ear-marked for the deluge to start from, which was to all appearances an unexpected origin of the doom of the wretched people.
