Allah Almighty had blessed Imam Zayn al-Abidin (may Allah have mercy on him) with a very beautiful body. When he passed away and the ritual washer (Ghassal) began to bathe him, he noticed that there was a black mark on his shoulder. He could not understand why this black mark was there. When the family members were asked, they also said that they did not know. When a few days passed, voices arose from the homes of the weak and disabled of that area, saying, "Where has the one gone who used to give us water to drink?" Then it was discovered that in the darkness of the night, Imam Zayn al-Abidin (may Allah have mercy on him) used to carry a water-skin filled with water on his shoulder to provide water to their homes. And he kept this secret hidden in such a way that no one found out about it throughout his entire life. (Al-Bidayah wan-Nihayah: 1339, Hilyat al-Awliya: 1363) This is the life of faith, where a person is serving others and showing empathy, yet is not seeking even a mere "thank you" in return. He is serving humanity solely for the pleasure of Allah, the Lord of Honor.
