1. Abu Hurayra said:

“The Prophet ﷺ said, ‘A child cannot repay his father unless he finds him as a slave and then buys him and sets him free.’” (Authentic)

Commentary:
It is as if the slave is non-existent and that by his freedom he comes into existence such that the child’s action here, is as that of his parent through whom he came into existence from non-existence.

2. Abu Burdah bin Abu Musa related that:

Ibn ‘Umar saw a Yemeni man going around the House making tawaf while carrying his mother on his back and chanting:
“I am her humble camel, if her riding animal breaks loose I remain in her service.”
Then the man asked, “Ibn ‘Umar, do you think that I have repaid her?”

He replied, “No, not even for a single groan (of the birth pangs she suffered).”
Then Ibn ‘Umar performed tawaf and came to Maqam (Ibrahim) and prayed two raka’at. He said, “O Ibn Abu Musa, every two raka’at make up for everything (expiates) that has happened before them. (Authentic Chain)

Commentary:
The pains of childbirth and nursing endured by the mother and the tremendous reward and high rank she earns as a result are highlighted in this hadeeth. Therefore, the parents must be shown kindness and great respect. The Tawaf and performance of the two units of prayer after it behind the station of Ibrahim are two major means to seek expiation of sins.

3. ‘Abdullah bin ‘Amr said:

“A man came to the Prophet ﷺ and made a pledge to him that he would do hijrah (emigrate). He had left his parents weeping.”

He i.e. the Prophet ﷺ said, “Go back to them and make them laugh as you made them weep.” (Authentic)

Commentary:
This further evinces the virtue of dutifulness to parents and warns against being sources of sadness to them. The necessity of correcting mistakes also forms a point of benefit in the hadeeth.

4. Abu Murra, the mawla of Umm Hani bint Abu Talib said that he rode with Abu Hurayra to his land in al-‘Aqiq (valley). When he entered his land, he shouted in his loudest voice, “Peace be upon you, mother, and the mercy of Allah and His blessing.”

She replied, “And peace be upon you and the mercy of Allah and His blessing.”

He said, “May Allah have mercy on you as you raised me when I was a child.”

She replied, “My son, may Allah reward you well and be pleased with you as you were dutiful towards me when old.”
Musa (one of the narrators of this Hadith) said, “The name of Abu Hurayra was ‘Abdullah b. ‘Amr.” (Sound Chain)

Commentary:
From what gladdens parents is the child’s dutifulness to them and Abu Hurayra’s mother showed appreciation in the best manner by saying: Jazaakallahu khayran (meaning: may Allah reward you well). As regards Abu Hurayra’s name, Imam Adh-Dhahabee (رحمه الله) said: “There is some variance on what his actual name is. However, the most preponderant is Abdur-Rahman bin Sakhr.”
