Zikr
of Allah
, [that is, Bismillahi
Rahmaani Raheem (in the Name of Allah
the Beneficent the Merciful) 
] is
in its start and then comes Allahu Akbar (Allah is the Greatest)
that is, the Takbeer
e Tahreema. After this, all Assalaat (Prayers) has the Zikr
of Allah
Almighty
and its start and end, all is the Zikr
of Allah.
Hazrat
Muhammad
Sal
Allahu Alaihe Wa Aa-lehee Wa-sallam
said that: the preeminent Zikr is Laaa-Ilaaha Ill-Allahu
Muhammad-ur-Rasoolu-Allah
(Sal Allahu Alaihe Wa Aa-lehee Wa-sallam)
In
addition, when you recite the Holy Quran, first is the Zikr of Allah, that is, Bismillahi
Rahmaani Raheem (in the Name of Allah
the Beneficent the Merciful) 
Hence,
in the Bismillah
, the Name Allah
is also the Zikr of
Allah.
When the Revelation (Wahi ) was revealed on the Holy Prophet of Allah Hazrat
Muhammad
Sal
Allahu Alaihe Wa Aa-lehee Wa-sallam
,
first of all this was said:
Allah Almighty
says: Read: in the name of your Lord who created (96:1)
Lo! One should also do the Zikr
of Allah only
at time of his death or he recite Kalimah-e-Tayyeb (Laaa-Ilaaha
Ill-Allahu
Muhammad-ur-Rasoolu-Allah (Sal Allahu Alaihe Wa Aa-lehee
Wa-sallam)
or should
say the Name Allah or recite the
Kalimah e Shahadat. All are the Zikr of Allah. Moreover,
Angels also ask the name of your God in the grave and this is also the Zikr
of Allah. The Name Allah will be on the top
of the Account (Deed Manifest). That Account (Deed Manifest) will
be given in the right hand and will be weighed in the Beam Balance
(Scale). That Pane, which will have the Name Allah,
will become the heaviest. And that person, who will say Allah on
the Pul-Siraat , the Hell will feel fear from it and he will cross over
the Pul-Siraat peacefully. With this Name Allah,
the Gate of the Paradise will open and at the time of Didaar,
that person, who will say Allah, he will become Mast
and the Kaamil Tajalli will take place and it will last forever.
Hence, that person, who laughs at and makes fun of the Name
Allah
or
he feels anger unto the Name Allah
or keeps enmity with Name
Allah, he
is damned. Such person will never be without three philosophies [and it is sure
that] either he is Kaafir or hypocrite or Faasiq
(Miscreant) same as in the blessed period of Hazrat
Muhammad
Sal
Allahu Alaihe Wa Aa-lehee Wa-sallam,
all the three types of such people existed that is, Kuffaar and hypocrites and Faasiqeen (abominable
persons). That person, who stops (and impedes) the Zikr of Allah, he will be of
these people. Zikr is the pillar of Islam and Deen is standing
due to the Zikr. When the Holy Prophet Hazrat
Muhammad
Sal
Allahu Alaihe Wa Aa-lehee Wa-sallam
and his
Holy
Companions Radhi-ya-Allahu Ta-aala Anhum
fought
battles with the Kuffaar, they used to first chanted together the Name
Allah (in
loud voice before starting battle) and said Allahu Akbar
. Secondly, when one has to
wage Jihad with Nafs , it is even then started with the Name
Allah.
