Tawheed (Oneness of God)
Tawheed means that Allah swt is One. He has neither any colleague nor any partner. He is neither born of any parent nor has He any wife, children, or relatives.
In order to understand Tawheed better, the School of Ahle Bayt defines attributes of Allah swt. These have been grouped into two categories:
The positive/unequivocal attributes which are befitting Allah are called Sifat al-Thubutiyah. They are many in number, but eight of them are usually listed.
The negative/contradictory attributes which cannot be found in Allah swt because they are below His Dignity are called Sifat al-Salbiyah. Again, there are many, but like Sifat al-Thubutiyah only eight are listed generally.
