Bismillahi walhamdulillahi 'alaa rasulillah,
this is the story of Muadz Ibn Jabal that i'd really like to share, taken from book title "Indahnya Budi Pekerti" trans : "The Beauty of Akhlaq" by Imam Nawawi. it is a booklet of selected hadith/stories of sahabah/sahabiah.
One day, Abu Idris Al Khawlani in Dimshyq (Damascus), went to Masjid Al Kabeer. And in the masjid he saw a group of people sitting around one man. And he described the man as smiling very much and people were sitting around him asking questions. So Abu Idris Al Khawlani asked,
"Who is this man?"
and they answered him saying
"That is Muadz Ibn Jabal RA, the companion of the Prophet(pbuh)."
So Abu Idris Al Khawlani came the next day early in the morning before Salaatul Fajr, and he thought that he was the first one to enter the masjid but there he found Muadz Ibn Jabal RA praying in the masjid before Salaat. So Abu Ibris came to Muadz and sat behind him and waited for him to complete his prayer. After Muadz completed his prayer, Abu Idris went to him and said to him,
"Oh Muadz! I love you for the sake of Allah SWT!"
Muadz Ibn Jabal RA pulled Abu Idris closer and he asked him,
"Aal la hu Lillah?" "By Allah do you love me only for the sake of Allah SWT?"
So Abu Idris said, "Yes!"
So Muadz Ibn Jabal RA smiled and pulled him closer and said to him,
"Let me give you the good news for verily I heard the Prophet (pbuh) say, "Allah SWT said,
وجبت محبتي للمتحابّين فيّ
"Wajabat Muhabbati Li Mutahaabina fiya"
"My love is wajib upon those who love for my sake"
