The Zikr of Ism-e-Allah-Zaat has four stages (Allahu, Lillah, Lahoo, Hoo). The glorious name (Allahu) has the great quality that if first ' ' of (Allahu) is removed it becomes (Lillah) which means "for Allah", it is also Ism-e-Zaat. In the Holy Qur'an Allah says
Meaning: For Allah is whatever is in the heavens and in the earth.
If the first (Lam) of (Lillah) is removed, it becomes (Lahoo) which means " for Him". It is also Ism-e-Zaat as Allah says in Qur'an
Meaning: For Him is all the kingdom and glory and He has complete command over everything.
If second (Lam) is also removed it becomes ' ' (Hoo). ' ' (Hoo) is a pronoun for Allah as is used many times in Qur'an for Ism-e-Allah
Meaning: He ( ) is Allah, no one is to be worshipped except (Hoo)
Among these, Zikr of (Hoo) is Sultan-ul-Azkar.
Imam Razi Rehmat-ul-Allah Alayh says:
- (Hoo) is Ism-e-Azam.
- (Hoo) is the extreme and most elevated Zikr of Arifeen.
- Meaning: The Zikr of (Hoo) is the extreme stage Zikr of invokers.
- When (Hoo) dominates and overpowers the being of the reciter of Zikr ' ' (Hoo), due to frequent Zikr, there remains nothing in him except (Hoo). (Muhik-ul-Faqr Kalan)
