Abu Amir al-Hawzani narrates: Sayyiduna Abu Kabshah al-Anmari (may Allah be pleased with him) came to him and said: "Lend me your horse for stud, for I heard the Prophet (peace and blessings be upon him) say: 'Whoever lends (his horse) for stud, and another horse is born as a result, the one who gave it receives a reward like that of seventy horses he had given for riding in the way of Allah.'"
Ahmad and al-Tabarani recorded it, except that al-Tabarani's wording is: I heard the Prophet (peace and blessings be upon him) say: "Whoever lends his horse for stud to a Muslim, and another horse is born as a result, receives a reward like that of seventy horses he had given for riding in the way of Allah; and if no horse is born as a result, he receives the reward of giving one horse for riding in the way of Allah." The narrators of both reports are thiqat (trustworthy).
