The Quran

هُوَ اللَّهُ الَّذي لا إِلٰهَ إِلّا هُوَ المَلِكُ القُدّوسُ السَّلامُ المُؤمِنُ المُهَيمِنُ العَزيزُ الجَبّارُ المُتَكَبِّرُ ۚ سُبحانَ اللَّهِ عَمّا يُشرِكونَ

Muhammad Asad

God is He save whom there is no deity: the Sovereign Supreme, the Holy, the One with whom all salvation rests,¹ the Giver of Faith, the One who determines what is true and false,² the Almighty, the One who subdues wrong and restores right,³ the One to whom all greatness belongs! Utterly remote is God, in His limitless glory, from anything to which men may ascribe a share in His divinity!

Lit., "the Salvation" (as-salam): see surah 5, note 29.
For this rendering of muhaymin, see 5:48 - where this term is applied to the Qur'an - and the corresponding note 64.
Since the verb jabara - from which the noun jabbar is derived - combines the concepts of "setting right" or "restoring" (e.g., from a state of brokenness, ill-health, or misfortune) and of "compelhag" or "subduing (someone or something) to one's will", I believe that the term al-jabbar, when applied to God, is best rendered as above.
