Sayyiduna Salman al-Farsi (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Indeed, on the day Allah created the heavens and the earth, He created one hundred mercies, which are layered between the heavens and the earth. Out of these, He placed one mercy in the earth; because of this mercy, a mother shows kindness to her child and wild animals care for one another, while ninety-nine mercies He has reserved until the Day of Resurrection. When the Day of Resurrection comes, He will complete the hundred through this mercy."
