Ninety - Nine Names of Allah
The proper name which Islam uses for God is "ALLAH".  ALLAH means "One who deserves to be loved" and "into whom everyone seeks refuge."
 This word, grammatically speaking, is unique.  It has no plural and no feminine.  So this name itself reflects light upon the fact that Allah is One and Only One; he has neither any partner nor any equal,  The name cannot properly be translated by the word "God" because God can be transformed into "Gods" and "Goddesses."
 Two more frequently used names are Rahman and Rahim.
 Rahman signifies that Allah is Merciful and that his Mercy encompasses each and everything in the universe without any distinction on account of faith or belief.  He makes, creates and sustains everything and every man whether he be a Muslim or Kafir.
 Rahim signifies that the Mercy of Allah on the Day of Judgment will surround the true believers only, and that unbelievers and hypocrites will be left out.
 It is apparent that both of these names signify a distinct aspect of God's Mercy. His Mercy in this world, as signified by "Rahman" is general; and the life-hereafter, as signified by "Rahim" is special.
 It will be of interest to note that the word "Rahman" cannot be used except for Allah, while "Rahim" can be used for others also.
 That is why it has been told by Imams that "Rahman is a reserved name which denotes unreserved Mercy" and "Rahim is an unreserved name which denotes Reserved Mercy."

SIFAT-E-THUBUTIYYAH

The positive attributes which are befitting Allah are called Sifat-e-Thubutiyyah.  They are many in number, but only eight of them are usually mentioned.  They are:
1.QADEEM:  It means that Allah is Eternal, i.e., He has neither beginning nor end.  Nothing except Allah is eternal.
  2.QAADIR:  It means that Allah is Omnipotent, i.e., He has power over everything and every affair.
  3. AALIM:  It means that Allah is Omniscient, i.e., He knows everything.  Even our unspoken intentions and desires are not hidden from Him.
  4. HAI:  It means that Allah was always alive and will remain alive forever.
  5. MUREED:  It means that Allah has His own Will and discretion in all affairs.  He does not do anything under compulsion.
  6. MUDRIK:  It means that He is All-Perceiving, as "Sami" (All-Hearing), 'Baseer' (All-Seeing), 'Hadhir' (Omnipresent).  Allah sees and hears everything without any need of eyes or ears.
  7.  MUTAKALLIM:  It means that Allah is the Master of the World, i.e., He can create speech in anything as He did in a tree for Hadhret Musa (A.S.), and in the 'Curtain of Light' for our Holy Prophet (S.A.W.).
  8.  SADIQ:  It means that Allah is true in His words and promises.  It is impossible to fix any limit to His attributes.  This list is not exhaustive but essential to understand the Glory of Allah.
 The attributes are not acquired but are inherent in the conception of Divinity.

SIFAT-E-SALBIYYAH
The Negative Attributes which cannot be found in Allah because they are below His dignity, are called Sifat-e-Salbiyyah.  They are many, but like Sifat-e-Thubutiyyah, only eight are listed here.  They are:
1.  SHAREEK:  The word "Shareek" means a colleague or partner.  Allah has neither a colleague nor a partner in His Divinity.
  2.  MURRAKKAB:  This word means "compound" or "mixed".  Allah is neither made, nor composed of any material.  He cannot be divided even in the imagination.
  3.  MAKAAN:  It means "place".  Allah is not in a place because He has no JISM (body), and He is everywhere because His power and Knowledge is magnificently apparent everywhere.
  4.  HULOOL:  It means "eternity". Nothing enters into Allah nor does He enter into anything or anybody.  Therefore, the belief of Incarnation in any form is abhorrent to the conception of Divinity.
  5.  MAHALLE HAWADITH:  This means "Subject to changes" or incarnation.  Allah cannot change.
  6.  MAR-I:  It means "visible".  Allah is not visible.  He has not been seen, is not seen, and will never be seen.
  7.  IHTIYAJ:  It means "dependable" or "need".  Allah is not deficient in any virtue, so He does not need anything.  He is All-Perfect.
  8.  SIFAT-E-ZA-ID:  This means "added qualifications".  The attributes of Allah are not separate from His Being.  When we say that God is Omnipotent and Merciful, we do not mean that His Power and Mercy are something different from His Person.  We see that a child is born without any power, and then he acquires strength day by day.  It is so because power is not his person.  But God is not like this.  He is Power Himself; Knowledge Himself; Justice Himself; Virtue Himself; Truth Himself, and etc.
 It will thus be seen that according to Islam, ALLAH is the name of God perceived in the light of the above Positive and Negative Attributes.  In other words, ALLAH is the Creator of the Universe, Self-Existent, the Source of all Perfection, and free from all defects.
