The beginning of the journey of faith is silence and constant state of dhikr which will not only bring wisdom but light and internal vision from Allah SWT.
There are many different kinds of Dhikr one can perform:
Halaqaat (gatherings) where the knowledge of Allah is dispersed are a form of dhikr.
Recitation of quran is dhikr.
Chanting tasbeeh (Subhan Allah), tahmeed (Alhamdulillah), and Takbir (Allah-u-Akbar) is dhikr.
Dhikr of the angels is to say Subhan Allah wabi hamdi hee Subhan Allah al Azeem (Glory to Allah and Praise is to Him, Glory to Allah the Greatest.)
The most beloved Dhikr to Allah is the following:
La ilaha illAllahu Wahdahu La Shareeka lahu, lahulmulk, wa lahulhamd, yuhyee wa yumeet, wa huwa hayy la yumoot abadan abada Dhul Jalaali waal Ikram beyadihi alkhayr, wa huwa 'ala kulli Shay'in Qadeer.
(There is) none worthy of worship except Allah. He is only One. (There is) no partners for Him. For Him (is) the Kingdom. And for Him (is) the Praise. He gives life and acuses death. And He (is) Ali ve. He will not die, never, ever. Possessor of Majesty and Reverence. In His hand (is) the goodness. And He (is) the goodness. And He (is) on everything powerful.)
Allah SWT said in the Qur'an:
The most beautiful names belong to Allah. So call on him by them (7:180)
Allah SWT has many attributes mentioned in the Qur'an as well as in the sayings of the Prophet SAW. He (SWT) is known as The Merciful, The All-Powerful, The Wise, The Provider etc. Whatever phase of life a person is in, there is an attribute of Allah dealing with it. All the person needs to do to ask Allah's assistance or to achieve a certain quality is to call on Allah with that particular attribute. So an excellent form of Dhikr is to call on Allah by His most beautiful names.
May Allah SWT give us sincerity to be true seekers of knowledge and to obtain high spiritual status? May He (SWT) choose us to be among those who revive the true teachings of this religion which has the potential to cure any social, personal, spiritual diseases in this world.
