calls his people to the worship of the One True God

وَمَن يَرْغَبُ عَن مِّلَّةِ إِبْرَٰهِـۧمَ إِلَّا مَن سَفِهَ نَفْسَهُۥ ۚ وَلَقَدِ ٱصْطَفَيْنَـٰهُ فِى ٱلدُّنْيَا ۖ وَإِنَّهُۥ فِى ٱلْـَٔاخِرَةِ لَمِنَ ٱلصَّـٰلِحِينَ

Who but a fool would forsake the religion of Abraham? We have chosen him in this world and he will rank among the righteous in the Hereafter.

إِذْ قَالَ لَهُۥ رَبُّهُۥٓ أَسْلِمْ ۖ قَالَ أَسْلَمْتُ لِرَبِّ ٱلْعَـٰلَمِينَ

His Lord said to him, ‘Devote yourself to Me.’ Abraham replied, ‘I devote myself to the Lord of the Universe,’

وَوَصَّىٰ بِهَآ إِبْرَٰهِـۧمُ بَنِيهِ وَيَعْقُوبُ يَـٰبَنِىَّ إِنَّ ٱللَّهَ ٱصْطَفَىٰ لَكُمُ ٱلدِّينَ فَلَا تَمُوتُنَّ إِلَّا وَأَنتُم مُّسْلِمُونَ

and commanded his sons to do the same, as did Jacob: ‘My sons, God has chosen [your] religion for you, so make sure you devote yourselves to Him, to your dying moment.’
