(1) And your Ilah (God) is One Ilah (God - Allah), La ilaha illa Huwa (there is none who has the right to be worshipped but He), the Most Gracious, the Most Merciful.

(2) Allah! La ilaha illa Huwa (none has the right to be worshipped but He), Al-Hayyul-Qayyum (the Ever Living, the One Who sustains and protects all that exists). Neither slumber nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on the earth. Who is he that can intercede with Him except with His Permission? He knows what happens to them (His creatures) in this world, and what will happen to them in the Hereafter. And they will never compass anything of His Knowledge except that which He wills. His Kursi extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Most Great. [This Verse 2:255 is called Ayat-ul-Kursi ]

(3) Allah! La ilaha illa Huwa (none has the right to be worshipped but He), Al-Hayyul-Qayyum (the Ever Living, the One Who sustains and protects all that exists).

(4) He it is Who shapes you in the wombs as He wills. La ilaha illa Huwa (none has the right to be worshipped but He), the All-Mighty, the All-Wise.

(5) Allah bears witness that La ilaha illa Huwa (none has the right to be worshipped but He), and the angels, and those having knowledge (also give this witness); (He always) maintains His creation in Justice. La ilaha illa Huwa (none has the right to be worshipped but He), the All-Mighty, the All-Wise.

(6) Our Lord! We believe in what You have sent down, and we follow the Messenger [('Îsa (Jesus)]; so write us down among those who bear witness (to the truth i.e. La ilaha illallah - none has the right to be worshipped but Allah).

(7) Verily! This is the true narrative [about the story of 'Îsa (Jesus)], and La ilaha illallah (none has the right to be worshipped but Allah, the One and the Only True God, Who has neither a wife nor a son). And indeed, Allah is the All-Mighty, the All-Wise.

(8) Allah! La ilaha illa Huwa (none has the right to be worshipped but He). Surely, He will gather you together on the Day of Resurrection about which there is no doubt. And who is truer in statement than Allah?

(9) Such is Allah, your Lord! La ilaha illa Huwa (none has the right to be worshipped but He), the Creator of all things. So worship Him (Alone), and He is the Wakil (Trustee, Disposer of affairs, Guardian) over all things.

(10) Follow what has been revealed to you (O Muhammad صلى الله عليه وسلم) from your Lord, La ilaha illa Huwa (none has the right to be worshipped but He) and turn aside from Al-Mushrikun
