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; and My love is assured for two [people] who maintain ties with one another for My Sake; and 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]
