Umar ibn Abdul Azeez (may Allah have mercy on him) said
إِنِ اسْتَطَعْتَ فَكُنْ عَالِماً
Become a scholar if you are able
فَإِنْ لَمْ تَسْتَطِعْ فَكُنْ مُتَعَلِّماً
If you are not able, then be a student
وَإِنْ لَمْ تَسْتَطِعْ فَأَحَبَّهُمْ
If you can not, then show love for them
وَإِنْ لَمْ تَسْتَطِعْ فَNot َتَبْغَضُهُمْ.
If you are unable to do that, then (at least) do not hate them
