Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever has sent three children ahead (i.e., who have died), they will become a barrier for him from Hell.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: If three minor children of a Muslim husband and wife pass away, Allah Almighty, out of His great mercy, will admit them into Paradise along with their children. When it will be said to those children, "Enter Paradise," they will say, "Let our parents come (and then we will enter)." This will be said to them three times, and each time they will give the same reply. Finally, it will be said to them, "You and your parents, all of you, enter Paradise."

Abu Hassan says: My two sons passed away, so I said to Sayyiduna Abu Hurairah (may Allah be pleased with him): Narrate to us any hadith of the Messenger of Allah (peace and blessings be upon him) that would comfort our souls regarding our deceased. He said: Yes, the Messenger of Allah (peace and blessings be upon him) said: The young children (of the believers) will be the little birds of Paradise (meaning, they will come and go in Paradise without restriction). Such a child will meet his father or his parents, will take hold of his hand, just as I have taken hold of the edge of your garment, and will not let go, until Allah, the Exalted, admits him and his father both into Paradise.

Sayyiduna Qurrah (may Allah be pleased with him) narrates that a man used to come to the Prophet Muhammad (peace and blessings be upon him), and his child would be with him. One day, the Prophet (peace and blessings be upon him) said to him: "Do you love him?" He replied: "O Messenger of Allah! May Allah love you as I love him." Then the Prophet (peace and blessings be upon him) missed him and asked: "What happened to the son of so-and-so?" The people said: "O Messenger of Allah! He has passed away." The Prophet (peace and blessings be upon him) said to his father: "Do you not like that whenever you come to any door of Paradise, you find your child waiting for you there?" A man asked: "O Messenger of Allah! Is this only for him or for all of us?" The Prophet (peace and blessings be upon him) replied: "Why not, it is for all of you."

Hassan bin Kareeb says: A child among us passed away, and his parents were deeply grieved. The Companion of the Messenger of Allah, Sayyiduna Hoshab (may Allah be pleased with him), said: Shall I tell you what I heard the Messenger of Allah (peace and blessings be upon him) say regarding a son like your son? The details are as follows: There was a Companion who had a son; he had taught him manners, or the child was still crawling on the ground, dragging his hands and feet. That child used to come with his father to the Prophet Muhammad (peace and blessings be upon him). Then it happened that the child passed away, and his father felt so much grief that he did not come to the Prophet (peace and blessings be upon him) for six days. One day, the Prophet (peace and blessings be upon him) asked: What is the reason that so-and-so is not seen? The people said: O Messenger of Allah! His child has passed away, and he is distressed because of it. The Prophet (peace and blessings be upon him) said: O so-and-so! Tell me, do you wish that your child was with you now and was the most active among the children? Or do you wish that your child was the most courageous among the children? Or do you prefer that your child was a strong youth of thirty to fifty years? Or do you wish that on the Day of Resurrection it will be said to you: Enter Paradise as a reward for the child who was taken from you?

Narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him), he says: My maternal aunt’s son, Sayyiduna Haritha (may Allah be pleased with him), went with the Messenger of Allah (peace and blessings be upon him) on the day of Badr. This boy had gone to watch the battle, not to fight, but suddenly an arrow struck him and he was killed. So my aunt came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! My son Haritha (may Allah be pleased with him), if he is in Paradise, then I will be patient seeking reward, otherwise Allah will see what I do. The Prophet (peace and blessings be upon him) said: O Umm Haritha! There are many gardens in Paradise, and indeed Haritha is in the highest Firdaus.
