It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When you see someone buying or selling in the mosque, say: May Allah not make your trade profitable. And when you see someone announcing a lost item in the mosque, say: May Allah not return it to you." This hadith is sahih (authentic) on the condition of Muslim, and the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) ordered him to equip an army, but the camels ran short. So the Messenger of Allah (peace and blessings be upon him) ordered me to take camels (on credit) against the young camels of the sadaqah, and I would take one camel in exchange for two camels (on the promise of giving them in the future). This hadith is sahih (authentic) on the condition of Muslim, and the two Shaykhs (Bukhari and Muslim) did not record it.
