In the Holy Qur'an, we see confirmation by God that there is indeed life on other Planets.
"Seek they then other than Allah's religion ? Andto Him submits whoever is in the heavens and the earth-" -- Suraht A1 Iraran (The Family of Imaran).
"All those in the heavens and the earth ask of Him. Every moment He is in a state (of glory). Suraht AI: Rahman (The Beneficent).
"And thy Lord best knows those who are in the heavens and the earth." Suraht Al-Israa
(The Ascension ) -
"There is none in the heavens and the earth but comes to the Beneficent as a servant-" Suraht Maryam (Mary)-
"Seest thou not that to Allah makes submission whoever is in the heavens and whoever is in the earth." -Suraht A1-Hajj (The Pilgrimage).
"Seest thou not that Allah is He, Whom do glo~2ify all those who are in the heavens and the earth-" --Suraht Al-Nur (The Light).
"Say: No one in the heavens and the earth knows the un. seen but Allah." Suraht A1-Naml. (The Ant)
"And the day when the trumpet is blown then those in the heavens and those in the earth will be struck with terror'' Suraht Al-Naml. (The Ant)
"And the trumpet is blown, 'So all those ~n the heavens and all those in the earth will swoon." -- Suraht Al-Zumar (The Companies).
"And He is whosOever is in the heavens and the earth. All are obedient to Him." --Suraht Al-Rum (The Romans ).
"And of His signs is the creation of the heavens and the earth and what He has spread forth in both of them of living beings. And He is All-powerful to gather them together, when He will," --Suraht A1-ShUra (The Council).
"And to Allah makes obeisance every living creature that is in the heavens and that is in the earth, and the angels (too) and they are not proud." -- Suraht A1-Nahl (The Bee).
The last verse may be one of the clearest verses of the Holy Qur'an which differentiates between angels and other creatures living in the heavens.
