It is narrated from Sayyiduna Qays bin Sala' al-Ansari (may Allah be pleased with him) that his brothers complained about him to the Messenger of Allah (peace and blessings be upon him) and said: "He squanders his wealth and spends it lavishly." So the Messenger of Allah (peace and blessings be upon him) said to him: "O Qays! What is the matter with your brothers that they complain about you? They claim that you squander your wealth and spend it freely." I said: "O Messenger of Allah! I take my share of the fruit and spend it in the way of Allah and on those who keep company with me." The narrator said: Then the Messenger of Allah (peace and blessings be upon him) struck him on his chest and said three times: "Spend, and Allah will spend on you." Then after that, when I went out in the way of Allah, I had a riding camel with me, and (Qays, may Allah be pleased with him) said: "Today I am the wealthiest of my household and the most well-off."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Qays bin Sala' (may Allah be pleased with him) only with this chain; Sa'd Abu Asim is alone in narrating it."
