Hizb 20 opens with one of At-Tawba's most frequently cited warnings, directed at religious leaders who wrongfully consume the wealth entrusted to them and at anyone who hoards gold and silver without spending in God's cause, promising a severe reckoning for the practice. The sura then restates the sanctity of certain months in the traditional calendar and rebukes those within the community who dragged their feet before joining a difficult military expedition rather than declaring their unwillingness outright.
Within this stretch falls the well known reference to the Prophet and his companion, generally identified as Abu Bakr, sheltering together in a cave during their emigration from Mecca, described as the second of two, with God as a third presence reassuring them not to grieve while their pursuers stood outside unaware, a passage frequently invoked in later devotional writing about that companion's closeness to the Prophet.
The hizb closes by drawing a sharp distinction between hypocrites who search for any pretext to avoid hardship and believers who accept a valid excuse, illness, poverty, or a genuine lack of means, without inventing one where none exists, closing on the principle that sincerity of intention matters as much as the outward act of joining or not joining the expedition.
