Following the guidance of previous prophets

أُو۟لَـٰٓئِكَ ٱلَّذِينَ هَدَى ٱللَّهُ ۖ فَبِهُدَىٰهُمُ ٱقْتَدِهْ ۗ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا ۖ إِنْ هُوَ إِلَّا ذِكْرَىٰ لِلْعَـٰلَمِينَ

Those are the ones whom Allāh has guided, so from their guidance take an example. Say, "I ask of you for it [i.e., this message] no payment. It is not but a reminder for the worlds."
