It is narrated from ‘Adi bin Hatim Ta’i (may Allah be pleased with him) that he asked the Messenger of Allah (peace and blessings of Allah be upon him): Which charity is the best? He replied:“Giving a slave as a gift in the way of Allah (to a Mujahid), or providing shade with a tent (for the Mujahideen), or giving a young she-camel in the way of Allah.” Imam Tirmidhi says:
1- This hadith has also come from Mu’awiyah bin Salih through a mursal chain,
2- In some chains (turuq), Zaid (bin Hubab) has been contradicted; this hadith has been narrated by Walid bin Jameel from Qasim Abu Abdur Rahman, Qasim from Abu Umamah, and Abu Umamah from the Prophet (peace and blessings of Allah be upon him); this hadith has been narrated to us by Ziyad bin Ayyub.
