Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said to me: "O Abu Hurayrah, visit at intervals, and love will increase."
Imam al-Bazzar recorded it, and Imam al-Tabarani recorded it in al-Mu'jam al-Awsat. Imam al-Bazzar said: No authentic hadith is known on this subject.
