Amr bin Dinar عمرو بن دينار الأثرم الجمحي · The Book on Virtues of Jihad

That the Messenger of Allah (ﷺ) said: "The most virtuous of charitable spending is the shade of a tent in the cause of Allah, or giving a servant in the cause of Allah, or a riding camel in the cause of Allah." This Hadith is Hasan Gharib Sahih, and it is more correct to me than the narration of Mu'awiyah bin Salih.
