It is narrated from Sayyiduna Abu Abdullah al-Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) saw a man who was not completing his bowing and prostration (in prayer), so he (peace and blessings be upon him) said: "If this man dies in this state, he will certainly die upon a way other than the religion (millah) of Muhammad (peace and blessings be upon him). So complete the bowing and the prostration fully, for the likeness of one who prays without completing his bowing and prostration is that of a hungry person who eats only one or two dates, which do not help him against his hunger in the least." Abu Salih (may Allah have mercy on him) says: I met Sayyiduna Abu Abdullah (may Allah be pleased with him) and asked: Who narrated this hadith to you, (saying) that he heard it directly from the Messenger of Allah (peace and blessings be upon him)? He said: The commanders of the armies, Sayyiduna Khalid bin al-Walid, Sayyiduna Shurahbil bin Hasanah and Sayyiduna Amr bin al-As (may Allah be pleased with them), narrated this hadith to me, (saying) that they heard it themselves from the Messenger of Allah (peace and blessings be upon him).
