Remembering God's will before making commitments or promises .

This hadith is about the importance of saying “If Allah wills” when making a vow. It was narrated from Abu Hurairah, who attributed it to the Prophet that Prophet Sulaiman said he would go around to ninety women and each would bear a child who will fight in the cause of Allah. However, he did not say “if Allah wills” and only one woman bore half a person. The Messenger of Allah then said that if he had said “if Allah wills” then his vow would not have been broken and this could have been a means for him to get what he wanted. This teaches us that we should always remember to say “if Allah wills” when making any kind of promise or commitment as it can help us achieve our goals in life with His permission.
