Dought & clear, - Is there life on other planets?.

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"
[al-Shoora 42:5]
"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"
[Fussilat 41:38]
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 inSaheeh al-Tirmidhi.
Inal-Saheehaynit 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.
