Musnad Ahmad Hadith 13796

It is narrated from Anas (may Allah be pleased with him) that it was the habit of Abdullah bin Rawahah (may Allah be pleased with him) that whenever he met any of his companions, he would say to him, "Come, let us believe in our Lord for a little while." One day he said the same thing to a man, so he became angry and went to the Prophet (peace and blessings of Allah be upon him) and said, "O Messenger of Allah (peace and blessings of Allah be upon him)! Just look at Ibn Rawahah, he is turning people away from believing in you and inviting them to believe for a little while." The Prophet (peace and blessings of Allah be upon him) said, "May Allah shower His mercy on Ibn Rawahah, he loves those gatherings upon which the angels boast."
