Hadith (Bukhari)
Is not a believer the one who eats one's fill while his neighbor is hungry.

Ata-Allah Al-Iskandari
Here I am! I am coming closer to You by my need for You!

Al 'Arabî Ad-Darqawi
Our Master (that God be satisfied with him) said: When your heart is empty from beings, it fills up with The Being; consequently, love is born between you and the others. If you act in a pure way with your Creator, all the creatures will be benevolent to you.

Hadith (Tirmidhi, Iman, Ibn Maja)
Those which God likes more are its lonely servants... those whose only refuge is their religion. In the last day of the judgment they will be led in front of Jesus son of Mary, that peace be on him.

Abu Yazid al Bistami
Love those which God loved (Awliya' Allah) and act in a way to be loved by them, because God looks into the heart of his saints seventy times per day and each night. Perhaps He will find your name in the heart of one of them. He will love you then and will cover you with His forgiveness.

Al Sulami
The futuwah is to treat people in the same way that one would like to be treated. A hadith of Bukhari from the Prophet (pbuh): - Wish for the others what you would wish for yourself, you would then be a true believer.

Al Mutanabbi
In me entered the pain of love like a poison mixed with honey. I enjoyed myself with it and in this delight was death.
