The word(s) "falling" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) Do you not see that Allah has subjected to you whatever is on the earth and the ships which run through the sea by His command? And He restrains the sky from falling upon the earth, unless by His permission. Indeed Allah, to the people, is Kind and Merciful.

(2) And if they were to see a fragment from the sky falling, they would say, "[It is merely] clouds heaped up."
