Oneness, Uniqueness of Allah (Tawheed)
Bukhari :: Book 9 :: Volume 93 :: Hadith 593
Narrated Abu Huraira:
Allah's Apostle said, "Allah created the creation, and when He finished from His creation the Rahm (womb) got up, and Allah said (to it). "Stop! What do you want? It said; "At this place I seek refuge with You from all those who sever me (i.e. sever the ties of Kinship.)" Allah said: "Would you be pleased that I will keep good relation with the one who will keep good relation with you, and I will sever the relation with the one who will sever the relation with you. It said: 'Yes, 'O my Lord.' Allah said (to it), 'That is for you.'' And then Abu Huraira recited the Verse:-- "Would you then if you were given the authority, do mischief in the land, and sever your ties of kinship." (47.22)
