Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I heard the Prophet (peace and blessings be upon him) saying: "Whoever gives a pledge of allegiance and then breaks it, when he comes before Allah Almighty, his right hand will not be with him."
(Allamah al-Haythami says:) I say: another hadith (on this subject) besides this one is also reported from this Companion.
This narration has been recorded by Imam al-Tabarani in al-Mu'jam al-Awsat. Its chain contains one narrator, Musa bin Sa'd, and he is majhul (unknown).
