`Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said to Sayyiduna Ubayy (may Allah be pleased with him): "Allah has commanded me to recite to you Surah (Al-Bayyina): 'Those among the People of the Book who disbelieved and the polytheists were not going to desist until there came to them clear evidence....'" Sayyiduna Ubayy (may Allah be pleased with him) asked, "Did Allah mention me by name?" The Prophet (peace and blessings be upon him) replied, "Yes." So Sayyiduna Ubayy (may Allah be pleased with him) began to weep.
