I was under debt and I came to the Messenger of Allah (ﷺ) and begged from him regarding it. He said: Wait till we receive Sadaqa, so that we order that to be given to you. He again said: Qabisa, begging is not permissible but for one of the three (classes) of persons: one who has incurred debt, for him begging is permissible till he pays that off, after which he must stop it; a man whose property has been destroyed by a calamity which has smitten him, for him begging is permissible till he gets what will support life, or will provide him reasonable subsistence; and a person who has been smitten by poverty. the genuineness of which is confirmed by three intelligent members of this peoples for him begging is permissible till he gets what will support him, or will provide him subsistence. Qabisa, besides these three (every other reason) for begging is forbidden, and one who engages in such consumes that what is forbidden.
Sahih Muslim Book 12, Hadith 141
As he was being brought to Allah's Apostle (ﷺ) I saw Ma'iz b. Malik-a short-statured person with strong sinews, having no cloak around him. He bore witness against his own self four times that he had committed adultery, whereupon Allah's Messenger (ﷺ) said: Perhaps (you kissed her or embraced her). He said: No. by God, one deviating (from the path of virtue) has committed adultery. He then got him stoned (to death), and then delivered the address: Behold, as we set out for Jihad in the cause of Allah, one of you lagged behind and shrieked like the bleating of a male goat, and gave a small quantity of milk. By Allah, in case I get hold of him, I shall certainly punish him.
