It is narrated from Sayyiduna Mu'adh (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: If three children of a Muslim husband and wife pass away, Allah Almighty will admit them into Paradise due to His immense mercy upon them. The people asked: O Messenger of Allah! What if there are two children? He (peace and blessings be upon him) said: Even if there are two. The people again asked: What if there is one? He (peace and blessings be upon him) said: Even if there is one. Then he (peace and blessings be upon him) said: By the One in Whose hand is my soul! Indeed, the incomplete child will pull his mother towards Paradise by the cut part of the umbilical cord, provided she remains patient seeking reward for it.
