Narrated Zaid bin Arqam: When `Abdullah bin Ubai said, Do not spend on those who are with Allah's Messenger , and also said, If we return to Medina, I informed the Prophet of his saying. The Ansar blamed me for that, and `Abdullah bin Ubai swore that he did not say. I returned to my house and slept. Allah's Messenger then called me and I went to him. He said, Allah has confirmed your statement. The Verse: They are the one who say: Spend nothing......(63.7) was revealed.
