1. Allah has created Angels out of light and gave them various duties to perform.
2. They are not visible to us.
3. They do not commit any sins nor do they disobey Allah.
4. They do what Allah has ordered.
5. We do not know their exact number.
6. We know of four famous Angels. They are: –

JIBRAEEL Alayhis Salaam.
MICHAEEL Alayhis Salaam.
IZRAAELL Alayhis Salaam.
ISRAFEEL Alayhis Salaam.

JIBRAEEL (Alayhis-Salaam) brought Allah's Books, Orders and messages to all the Prophets. He was also sent to help the Prophets at times and fight against their enemies.

MICHAAEEL (A.S.) is in charge of food and rain. Other Angels work under him who are in charge of clouds, the seas, the rivers and the winds. He gets the order from Allah. He then orders the others under his command.

IZRAAEEL (A.S.) takes away life with the order of Allah. He is in charge of death. Numerous Angels work under him. Some take away the lives of good persons whilst others looking very fearful take away the lives of sinners and disbelievers.

ISRAAFEEL (A.S.) will blow the SOOR (TRUMPET) on the day of judgement. The sound will destroy and kill everything that is on earth and in the skies. When he blows for the second time all will come to life with the order of Allah.

There are two Angels that are always with every person. One writes all his GOOD DEEDS whilst the other enters all his BAD DEEDS. They are known as: – KIRAAMAN-KAATIBEEN.

The MUNKAR and NAKEER question a person when he dies.

Some Angels are in charge of heaven, some of hell, some of looking after children, the old, the weak and others whom Allah wishes to protect.

From the QURAN and HADITH we come to know that various other angels are in charge of various other duties.
