It has been observed from some accounts that they offer "junk" under the guise of "for the sake of God" because they know it will be sold and they want to get rid of it without cost. Most of the "junk" offered is damaged, such as broken or torn furniture, or malfunctioning items, and the like. So beware, beware, brothers and sisters. Allah Almighty is good and accepts only good. As for "junk" and damaged items, you can write "no charge" and the name of Allah should only be mentioned in a manner befitting Him, Glorified be He. And everyone will be held accountable on the Day of Judgment for their words. Have I conveyed the message? O Allah, bear witness.
