It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he narrated it as a saying of the Prophet (peace and blessings be upon him), that he (peace and blessings be upon him) said: "Those who show mercy, al-Rahman shows mercy to them. Show mercy to those on the earth, and the One in the heaven will show mercy to you. The tie of kinship (al-rahim) is a branch from al-Rahman; so whoever joins it, Allah will join him, and whoever severs it, Allah will cut him off." Imam al-Hakim says: All of these chains are sahih (authentic). I have examined their chains exhaustively, mentioning the Companions, so that no one imagines that the two Shaykhs did not leave out any authentic hadith.
