I heard the Messenger of Allah ﷺ say, "Whoever lends out silver or gold, or gives milk to drink, or guides someone along a path, it is equivalent to freeing a slave."
سمعت رسول الله ﷺ يقول: من منح منيحة ورقا أو ذهبا أو سقى لبنا أو أهدى زقاقا فهو كعدل رقبة.
Ahmad (18403) and Bazzar in Kashf Astar (948) both narrated it from the hadith of Husayn bin Waqid, who said, "Simak bin Harb narrated to me, from Numan bin Bashir," and he related it. Its chain is hasan on account of Simak bin Harb, for there is disagreement about him, though there is no harm in him except in his narration from Ikrima, from Ibn Abbas, where he is inconsistent. Bazzar said, "We do not know of it from Numan except through this route." I did not find this hadith in Majma al-Zawaid in the chapter on what has been said about the loan-gift, but I found in some other copies mention of this hadith in that same chapter, and Haythami, after attributing it to Ahmad and to Tabarani in al-Kabir, said, "Its narrators are the narrators of the Sahih."As for what was narrated from Ibn Masud, from the Prophet ﷺ, who said, "Do you know which charity is best?" They said, "Allah and His Messenger know best." He said, "The loan-gift, that one of you lends his brother a dirham, or the back of a riding animal, or the milk of a sheep, or the milk of a cow." Its chain is daif. Imam Ahmad (4415) and Abu Yaala (5121) both narrated it from the hadith of Ibrahim Hijri, who said, "I heard Abu Ahwas narrate from Abdullah," and he related it. Ibrahim Hijri is Ibn Muslim Abdi, Abu Ishaq Hijri, known by his kunya, daif by the agreement of the scholars. As for Haythami's statement in al-Majma (1333), "The narrators of Ahmad are the narrators of the Sahih," this is not correct, for no one narrated from Ibrahim Hijri except Ibn Majah.However, Bazzar narrated it in Kashf Astar (947) from Amr bin Yahya Abali, who said, "Hafs bin Jamee narrated to us, from Simak, from Ibrahim bin Alqama, and Aswad, from Abdullah," raising it to the Prophet, who said, "Which charity is best?" They said, "Allah and His Messenger know best." He said, "That a man lends his brother dirhams, or the back of a riding animal." Bazzar said, "We do not know of anyone who narrated it this way except Hafs, and we did not hear it except from Amr."I say, Hafs bin Jamee Ajli was declared daif by Abu Hatim. Abu Zura said, "He is not strong." Ibn Hibban said, "He cannot be relied upon." See al-Mizan (1/556). And in al-Majruhin by Ibn Hibban (254), "A Kufan with objectionable narrations, who settled in Basra. He narrates from Simak bin Harb, and Ahmad bin Abdah Dabbi narrated from him. He was among those who erred until he went beyond the limit of being relied upon when he narrates alone." End of quote.
