In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Ubaadah Bin Saamit [radiyallaahu-anhu] said that he heard the Messenger of Allaah [sallal-laahu-alayhi-wasallam] saying that Allaah [The Most High] said:

حقَّت محبتي للمتحابين فيَّ

وحقت محبتي للمتواصلين في

وحقت محبتي للمتزاورين في

وحقت محبتي للمتباذلين في

My love is assured for two (people) who love one another for My Sake. My love is assured for two (people) who maintain ties with one another for My Sake. My love is assured for two (people) who visit one another for My Sake and My love is assured for two (people) who help one another (financially) for My Sake. [Ref 1]

And in another version reported by Ibn Hibbaan: [وحقت محبتي للمتناصحين في   – And my love is assured for two (people) who advise one another for My Sake. [Ref 2]
