Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "Whoever is called to give testimony and conceals it is like one who gives false testimony."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its chain contains Abdullah bin Salih, whom Abd al-Malik bin Shu'ayb bin al-Layth declared thiqah (trustworthy), saying: He is thiqah and ma'mun (reliable). A group declared him da'if (weak).
