The virtues of Surah An'am
On the authority of the Prophet (peace and blessings of Allaah be upon him): If I recite this surah, all the rewards for the creation of Allaah in the House of God will be on the door of the door, after all the water is good and water is high.

The Holy Prophet (peace and blessings of Allaah be upon him) said: “Whoever recites Surah al-An'am, for him will be a reward from the door, equal to the weight of all the cattle that God has created in the world, and for all the doors, one hundred thousand good deeds and One hundred thousand degrees is taken care of by him.
Surah al-An'aam (The Cattle)
This Surah was revealed in Makkah and contains a total of 165 verses. Imam Ridha (a.s.) has said that this Surah was revealed accompanied by the descending of seventy thousand angels. These angels will ask forgiveness from Allah (S.w.T.) for any person who recites this Surah, and they will continue doing so until the Day of Judgment.
Imam Ja'far as-Sadiq (as) has said that if a person writes this Surah using musk or saffron and then drinks it (ie. Puts the written Surah in water for its writing to dissolve) for six consecutive days, that person will be blessed abundantly and will be free from all problems and ailments. He will not loose his health or fall sick.
The 6th Holy Imam (a.s.) also said that this Surah must be accorded due respect as the name of Allah (S.w.T.) appears 70 times in it. If people knew the benefits of reciting this Surah, they would never leave it.
