I Love You for the Sake of Allah
One day while the Prophet, peace and blessings be upon him, was sitting with his Companions, a man passed by them. One of the ones sitting said, “I love this man.”
The Prophet, peace and blessings be upon him, wanted to know if he had told this man his feelings or not. So he, peace and blessings be upon him, asked him, “Did you tell him?”
The man replied, “No, I have not told him yet.”
The Prophet, peace and blessings be upon him, told him that if one loves his brother, he should tell him of his feelings. So the man got up and hurried to catch the other man.
Then he said to him, “I love you for the sake of Allah.”
The other man replied, “May Allah love you, as you loved me for His Sake.”
Thus, it is a Prophetic tradition that a Muslim tell his Muslim brother that he loves him for the Sake of Allah, and the other replies that he loves him, too, for the sake of Allah.
