Quran Verse 98:5

All that was asked of them was to worship God, devoting the religion absolutely to Him alone, observe the contact prayers (Salat), and give the obligatory charity (Zakat). Such is the perfect religion.

وَما أُمِروا إِلّا لِيَعبُدُوا اللَّهَ مُخلِصينَ لَهُ الدّينَ حُنَفاءَ وَيُقيمُوا الصَّلوٰةَ وَيُؤتُوا الزَّكوٰةَ وَذٰلِكَ دينُ القَيِّمَةِ

wa maa umiroo il-la liy’abu dul laaha mukhliseena lahud-deena huna faa-a wa yuqeemus salaata wa yu-tuz zakaata; wa zaalika deenul qaiyimah
