Abu Umamah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Providing shade with a tent for those engaged in jihad, giving a servant as a gift, and donating a young she-camel are the best and most superior forms of charity." __REF_N__ Imam Tirmidhi says: 1- This hadith is hasan sahih gharib, 2- In my view, it is more authentic than the narration of Mu'awiyah bin Salih.
