Is there life on other planets or in other galaxies?.
Praise be to Allaah.
As for the seven heavens, they are populated by the angels,
as Allaah says (interpretation of the meaning):
“Nearly the heavens might be rent asunder from above them
(by His Majesty), and the angels glorify the praises of their Lord, and ask
for forgiveness for those on the earth. Verily, Allaah is the Oft‑Forgiving,
the Most Merciful”
“But if they are too proud (to do so), then there are
those who are with your Lord (angels) glorify Him night and day, and never
are they tired”
Al-Tirmidhi (2312) narrated that Abu Dharr (may Allaah be
pleased with him) said: The Messenger of Allaah (peace and blessings of
Allaah be upon him) said: “Verily I see what you do not see and I hear what
you do not hear. The heaven is creaking and it should creak, for there is no
space in it the width of four fingers but there is an angel there,
prostrating to Allaah. By Allaah, if you knew what I know, you would laugh
little and weep much, and you would never enjoy women in your beds, and you
would go out in the streets, beseeching Allaah.” Classed as hasan by
al-Albaani in Saheeh al-Tirmidhi.
In al-Saheehayn it is narrated from Maalik ibn
Sa’sa’ah, in the story of al-Isra’ wa’l-Mi’raaj (the Prophet’s Night Journey
and Ascent into heaven): “ … Then the Much-Frequented House (al-bayt
al-ma’moor) was raised up for me, and I said: ‘O Jibreel, what is this?’ He
said: ‘This is the Much-Frequented House. Every day seventy thousand angels
enter it and when they depart from it, they never return to it.” Al-Bukhaari
(3207) and Muslim (164).
This has to do
with the heavens. As for the planets and other galaxies, our answer is to
say: Allaah knows best.
