It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that he (peace and blessings be upon him) offered the funeral prayer over his son Ibrahim, who was sixteen months old, and he (peace and blessings be upon him) said: "Indeed, there is for him in Paradise a wet nurse who will complete his suckling, and he is a siddiq (a truthful one)."
