quran:16:127 –

And be patient, ˹O Muhammad˺, and your patience is not but through Allah. And do not grieve over them and do not be in distress over what they conspire.  

So be patient, and your patience is only by ˹the help of˺ God, ˹only˺ by His assistance. And do not grieve for them, that is, ˹for˺ the disbelievers if they do not believe, despite your eagerness that they believe, nor be in distress because of that which they scheme, in other words, do not be concerned with their scheming, for I ˹God˺ will make victorious over them.
القرآن:١٦:١٢٧ –

وَاصْبِرْ وَمَا صَبْرُكَ إِلَّا بِاللَّهِ ۚ وَلَا تَحْزَنْ عَلَيْهِمْ وَلَا تَكُ فِي ضَيْقٍ مِمَّا يَمْكُرُونَ  

{واصبر وما صبرك إلا بالله} بتوفيقه {ولا تحزن عليهم} أي الكفار. إن لم يؤمنوا لحرصك على إيمانهم {ولا تك في ضيق مما يمكرون} أي لا تهتم بمكرهم فأنا ناصرك عليهم.
