The word(s) "membrane" appears 1 time(s) in 1 verse(s) in Quran in Saheeh International translation.

(1) He causes the night to enter the day, and He causes the day to enter the night and has subjected the sun and the moon - each running [its course] for a specified term. That is Allah, your Lord; to Him belongs sovereignty. And those whom you invoke other than Him do not possess [as much as] the membrane of a date seed.
