The Quran

وَما أُمِروا إِلّا لِيَعبُدُوا اللَّهَ مُخلِصينَ لَهُ الدّينَ حُنَفاءَ وَيُقيمُوا الصَّلاةَ وَيُؤتُوا الزَّكاةَ ۚ وَذٰلِكَ دينُ القَيِّمَةِ

Ali Unal

But they were not enjoined anything other than that they should worship God, sincere in faith in Him and practicing the Religion purely for His sake, as people of pure faith; and establish the Prayer in accordance with its conditions; and pay the Prescribed Purifying Alms. And that is the upright, ever-true Religion.¹

This summarizes God’s Religion, which He conveyed through all His Messengers. This Religion is Islam. For the last two verses, also see 3: 19, note 4.
