Allah says:
[فَادْعُواْ اللَّهَ
مُخْلِصِينَ لَهُ الدِّينَ وَلَوْ كَرِهَ الْكَـفِرُونَ ]
(So, call you upon Allah making religion sincerely for Him, however much the
disbelievers may hate.) This means, worship Allah and call upon Him alone in all
sincerity. Do not be like the idolators in conduct and beliefs. Imam Ahmad
recorded that after ending every prayer, `Abdullah bin Az-Zubayr used to say:
"There is no (true) God except Allah Alone with no partner or associate, His is
the dominion and praise, for He is able to do all things; there is no strength
and no power except with Allah; there is no (true) God except Allah and we
worship none but Him; to Him belongs the blessings and the virtue and good
praise; there is no (true) God except Allah, we worship Him in all sincerity
even though the disbelievers may hate that.'' He said, "The Messenger of Allah
used to say Tahlil with this after every prayer.'' Something similar was also
recorded by Muslim, Abu Dawud and An-Nasa'i. It was reported in Sahih from Ibn
Az-Zubayr, may Allah be pleased with him, that the Messenger of Allah used to
say the following after the prescribed (obligatory) prayers:
«لَا إِلهَ إِلَّا
اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ، وَهُوَ عَلى
كُلِّ شَيْءٍ قَدِيرٌ، لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ، لَا إِلهَ إِلَّا
اللهُ، وَلَا نَعْبُدُ إِلَّا إِيَّاهُ، لَهُ النِّعْمَةُ وَلَهُ الْفَضْلُ وَلَهُ
الثَّــنَاءُ الْحَسَنُ، لَا إِلهَ إِلَّا اللهُ مُخْلِصِينَ لَهُ الدِّينَ وَلَوْ
كَرِهَ الْكَافِرُون»
(There is no (true) God except Allah Alone with no partner or associate, His
is the dominion and praise, for He is able to do all things; there is no
strength and no power except with Allah; there is no (true) God except Allah and
we worship none but Him; His is the blessing and virtue and good praise; there
is no (true) God except Allah, we worship Him in all sincerity even though the
disbelievers hate that.)
[رَفِيعُ
الدَّرَجَـتِ ذُو الْعَرْشِ يُلْقِى الرُّوحَ مِنْ أَمْرِهِ عَلَى مَن يَشَآءُ مِنْ
عِبَادِهِ لِيُنذِرَ يَوْمَ التَّلاَقِ - يَوْمَ هُم بَـرِزُونَ لاَ يَخْفَى عَلَى
اللَّهِ مِنْهُمْ شَىْءٌ لِّمَنِ الْمُلْكُ الْيَوْمَ لِلَّهِ الْوَحِدِ
الْقَهَّارِ - الْيَوْمَ تُجْزَى كُلُّ نَفْسٍ بِمَا كَـسَبَتْ لاَ ظُلْمَ
الْيَوْمَ إِنَّ اللَّهَ سَرِيعُ الْحِسَابِ ]
(15. (He is Allah) Owner of high ranks and degrees, the Owner of the Throne.
He sends the revelation by His command to any of His servants He wills, that he
may warn of the Day of Mutual Meeting.) (16. The Day when they will come out,
nothing of them will be hidden from Allah. Whose is the kingdom this Day It is
Allah's, the One, the Irresistible!) (17. This Day shall every person be
recompensed for what he earned. This Day no injustice. Truly, Allah is swift in
reckoning.)
