Thikr (Remembrance of Allaah The Almighty) following prayer:
When the one who performs prayer finishes his prayer, then it is recommended for him to say: Astaghfirullaah (I ask Allaah for forgiveness) three times. Then say: Allaahumma anta as-salaam wa minka as-salaam tabaarakta ya dhaa’l-jalaali wa’l-ikraam (O Allaah, You are the One Who is free from all defects and deficiencies and from You is all peace, blessed are You, O Possessor of majesty and honor).
Then say: Laa ’ilaaha ’illallaahu wahdahu laa shareeka lahu, lahul-mulku, wa lahul-hamdu wa Huwa ‘alaa kulli shay’in Qadeer. Laa hawla wa laa quwwata ’'illaa billaahi, laa ’ilaaha ’illallaahu, wa laa na‘budu ’'illaa ’iyyaahu, lahun-ni‘matu wa lahul-fadhlu wa lahuth-thanaa’ul-hasanu, laa ’ilaaha ’illallaahu mukhliseena lahud-deena wa law karihal-kaafiroon, Allaahumma laa maani‘ limaa ’a‘tayta, wa laa mu‘tiya limaa mana‘ta, wa laa yanfa‘u thal-jaddi mink al-jadd (None has the right to be worshipped but Allaah alone, He has no partner, His is the dominion and His is the praise and He is Able to do all things. There is no power and no might except by Allaah. None has the right to be worshipped but Allaah, and we do not worship any other besides Him. His is grace, and His is bounty and to Him belongs the most excellent praise. None has the right to be worshipped but Allaah. (We are) sincere in making our religious devotion to Him, even though the disbelievers may dislike it, O Allaah, there is none who can withhold what You give, and none may give what You have withheld; and the might of the mighty person cannot benefit him against You).
Then say: Subhaan Allaah wa’l-hamdu Lillaah wa Allaahu akbar (Glory be to Allaah, praise be to Allaah and Allaah is most great) 33 times, and to complete one hundred one should say: Laa ilaaha ill-Allaah wahdahu laa shareeka lah, lahu’l-mulk wa lahu’l-hamd wa huwa ‘ala kulli shay’in qadeer (There is no god but Allaah Alone, with no partner or associate His is the sovereignty and to Him be praise, and He is Able to do all things).
Sometimes, one may say: Subhaan Allaah wa’l-hamdu Lillaah wa Allaahu akbar twenty-five times.
Some other times: one may say: Subhaan Allaah wa’l-hamdu Lillaah wa Allaahu akbar ten times.
Or one sometimes may say: Subhaan Allaah wa’l-hamdu Lillaah wa Allaahu akbar 33 times, then say: Allahu Akbar (in addition to the previous ones) to complete one hundred.
Then one should recite:
-Aayat al-Kursiy (Soorah 2: 255).
-Al-Mu‘awwithataan (Last two Soorahs of the Noble Quran).
