Concise Quran Commentary
If they had been telling the truth in their claim that they wanted to go out with the Messenger (peace be upon him), striving for the sake of Allah, they would have made preparations for it; but Allah did not want them to go with the Prophet, and stopped them from doing so. They were disgraced because they were told to stay behind with those who were ordered to stay behind, such as the women, children and the sick.
