Qur'an 52:44

And if they were to see a fragment of the heaven falling, they would say: A heap of clouds.

And if they should see a portion of the heaven coming down, they would say: Piled up clouds.

Kuma idan sun ga wani ɓaɓɓake daga samã yãnã fãɗuwa, sai su ce wani girgije ne, mai hauhawar jũna.

The Stubbornness of the Idolators; Their Punishment Allah the Exalted reaffirms the stubbornness of the idolators and their ignorance of what goes around them, وَإِن يَرَوْا كِسْفًا مِّنَ السَّمَاء سَاقِطًا يَقُولُوا سَحَابٌ مَّرْكُومٌ ﴿٤٤﴾ And if they were to see a piece of the heaven falling down, they would say: "Clouds gathered in heaps!'' meaning, on them as punishment, they would not believe it is coming their way, saying that, these are layers of clouds on top of each other. Allah the Exalted said in other Ayat, وَلَوْ فَتَحْنَا عَلَيْهِمْ بَابًا مِنَ السَّمَاءِ فَظَلُّوا فِيهِ يَعْرُجُونَ لَقَالُوا إِنَّمَا سُكِّرَتْ أَبْصَارُنَا بَلْ نَحْنُ قَوْمٌ مَسْحُورُونَ And even if We opened to them a gate from the heaven and they were to keep on ascending thereto (all day long), they would surely say (in the evening): "Our eyes have been dazzled. Nay, we are a people bewitched.'' (15:14-15) Allah the Exalted said, فَذَرْهُمْ ... So leave them alone, (`O Muhammad,') ... حَتَّى يُلَاقُوا يَوْمَهُمُ الَّذِي فِيهِ يُصْعَقُونَ ﴿٤٥﴾ till they meet their Day, in which they will sink into a fainting. (on the Day of Resurrection),
