The diversity in the human family should be the cause of love and harmony, as it is in music where many different notes blend together in the making of a perfect chord.
If Allah has written for you happiness, no one can steal that from you, and if He has written for your heart to break, then no-one can mend it but He, so always put your trust in Allah.
The essence of friendship is entireness, a total magnanimity and trust. It must not surmise or provide for infirmity. It treats its object as a god, that it might deify both.
