Be compassionate among yourselves
This is the meaning of the Holy Quran. It says about the Holy Prophet (s.w.a.), "Ardently anxious is he over you. To the believers is he most kind and merciful" [The Holy Quran, 9: 128]. He is kind to believers and "those who are with him are strong against unbelievers, but compassionate amongst each other" [The Holy Quran, 48: 29].
You should be strong against those who show enmity to you and who are your enemies. You should be firm against them. You should not be like a soft earthwork which the enemy can infiltrate easily. You should stand firm against the enemy, but you should be compassionate among yourselves. You should be honest with and kind to one another. Names should not be able to separate you. Geographical borders should not arouse hostility among you and they should not be able to pit nations against one another. This is one of the lessons of the Holy Prophet (s.w.a.). Today - which is the birthday anniversary of the Holy Prophet (s.w.a.) - we should learn his lessons. Mere praise of that great personality is not the only thing that is expected of us today. We should learn his lessons. We should achieve what the Holy Prophet (s.w.a.) was sent for. As I said, the primary thing in today's world of Islam is unity. I hope that Allah the Exalted helps us to succeed in doing what we say.
