وَإِذْ أَخَذْنَا مِيثَٰقَ بَنِىٓ إِسْرَٰٓءِيلَ لَا تَعْبُدُونَ إِلَّا ٱللَّهَ وَبِٱلْوَٰلِدَيْنِ إِحْسَانًۭا وَذِى ٱلْقُرْبَىٰ وَٱلْيَتَٰمَىٰ وَٱلْمَسَٰكِينِ وَقُولُوا۟ لِلنَّاسِ حُسْنًۭا وَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ ثُمَّ تَوَلَّيْتُمْ إِلَّا قَلِيلًۭا مِّنكُمْ وَأَنتُم مُّعْرِضُونَ
And (remember) when We made a covenant with the Children of Israel, (saying): Worship none save Allah (only), and be good to parents and to kindred and to orphans and the needy, and speak kindly to mankind; and establish worship and pay the poor-due. Then, after that, ye slid back, save a few of you, being averse.
Surah Al-Baqara(2:83)
