Hadith 4337
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Sayyiduna Sulaiman bin Dawood (peace be upon them) took an oath that he would go to his one hundred wives, and each woman among them would give birth to a boy who would fight in the way of Allah. The Prophet (peace and blessings be upon him) said: But only one woman gave birth to an incomplete child. The Prophet (peace and blessings be upon him) said: If he had said 'InshaAllah' at that time, it would have happened as he had stated."
