prophetic mission and da'wah (calling to Allah)

لِّكُلِّ أُمَّةٍ جَعَلْنَا مَنسَكًا هُمْ نَاسِكُوهُ ۖ فَلَا يُنَـٰزِعُنَّكَ فِى ٱلْأَمْرِ ۚ وَٱدْعُ إِلَىٰ رَبِّكَ ۖ إِنَّكَ لَعَلَىٰ هُدًى مُّسْتَقِيمٍ

For every [religious] community We have appointed rites which they perform. So, [O Muḥammad], let them [i.e., the disbelievers] not contend with you over the matter but invite [them] to your Lord. Indeed, you are upon straight guidance.

وَلَا يَصُدُّنَّكَ عَنْ ءَايَـٰتِ ٱللَّهِ بَعْدَ إِذْ أُنزِلَتْ إِلَيْكَ ۖ وَٱدْعُ إِلَىٰ رَبِّكَ ۖ وَلَا تَكُونَنَّ مِنَ ٱلْمُشْرِكِينَ

And never let them avert you from the verses of Allāh after they have been revealed to you. And invite [people] to your Lord. And never be of those who associate others with Allāh.
