In a narration transmitted from Khalid, the words are: he says: My father narrated to me from my grandfather
this narration; he says: "The Prophet (peace and blessings be upon him) asked me: 'Do you love Paradise?' (The narrator says:) I said: 'Yes!' The Prophet (peace and blessings be upon him) said: 'Then love for your brother what you love for yourself.'"
Abdullah, and al-Tabarani in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat, recorded something similar, and its narrators are thiqat (trustworthy).
