Jami` at-Tirmidhi 1627
جامع الترمذي#1627SahihNarrated Abu Umamah: 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." [Abu 'Eisa said:] This Hadith is Hasan Gharib Sahih, and it is more correct to me than the narration of Mu'awiyah bin Salih
