Sayyiduna Abdullah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Whoever lends silver twice, it is equal to giving it in charity once."
Sulayman bin Yusayr narrated it this way, and al-Bukhari said: He is not strong. Others narrated it from Abdullah bin Mas'ud as his own saying, and its attribution to the Prophet (peace and blessings be upon him) is weak.
