Hadith 2515
It is narrated from Abu Abdur Rahman Hubli that Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) was in an army when children and their mothers were separated. He saw the children and they were crying, so each child was returned to his mother. And he used to say: Indeed, the Messenger of Allah (peace and blessings be upon him) said: "Whoever separates a mother from her child, Allah Almighty will separate him from his loved ones on the Day of Resurrection."
