Islam

Ibn Abi Haatim narrated in his Tafseer from Abu Ja'far, from al-Rabee'
ibn Anas, that Abu'l-Aaliyah said:
The companions of the Messenger of Allaah (peace and blessings of
Allaah be upon him) thought that nosin could do harm if one was
sincere and that no good deed was of any availif one associates others
with Allaah. Then Allaah revealed the words (interpretation of the
meaning):
"O you who believe! Obey Allaah, and obey the Messenger (Muhammad) and
render not vain your deeds"
[Muhammad 47:33]
