(During the early days of Islam), the inheritance used to be given to one's offspring and legacy used to be bequeathed to the parents, then Allah cancelled what He wished from that order and decreed that the male should be given the equivalent of the portion of two females, and for the parents one-sixth for each of them, and for one's wife one-eighth (if the deceased has children) and one-fourth (if he has no children), for one's husband one-half (if the deceased has no children) and one-fourth (if she has children).

The Prophet said, "The biggest sins are: To join others in worship with Allah; to be undutiful to one's parents; to kill somebody unlawfully; and to take an oath Al-Ghamus.

A man said to the Prophet, "Shall I participate in Jihad?" The Prophet said, "Are your parents living?" The man said, "Yes." the Prophet said, "Do Jihad for their benefit."

We used to strike the drunks with our hands, shoes, clothes (by twisting it into the shape of lashes) during the lifetime of the Prophet, Abu Bakr and the early part of `Umar's caliphate. But during the last period of `Umar's caliphate, he used to give the drunk forty lashes; and when drunks became mischievous and disobedient, he used to scourge them eighty lashes.

(While in the company of my parents) I was made to perform Hajj with Allah's Apostle and I was a seven-year-old boy then. (Fath-ul-Bari, p.443, Vol.4)

Allah's Apostle said, "Shall I inform you of the biggest of the great sins?" They said, "Yes, O Allah's Apostle!" He said, "To join partners in worship with Allah, and to be undutiful to one's parents. "

A man came to the Prophet asking his permission to take part in Jihad. The Prophet asked him, "Are your parents alive?" He replied in the affirmative. The Prophet said to him, "Then exert yourself in their service."

Yahya related to me from Zayd ibn Aslam from a man of the Banu Damra that his father said, "The Messenger of Allah, may Allah bless him and grant him peace, was asked about the Aqiqa. He said, 'I do not like disobedience (uquq),' as if he disliked the name. He said, 'If anyone has a child born to him, and wants to sacrifice for his child, then let him do it.' "

Malik said, "The generally agreed on way of doing things among us about which there is no dispute and what I have seen the people of knowledge in our city doing is that when a father inherits from a son or a daughter and the deceased leaves children, or grandchildren through a son, the father has a fixed share of one sixth. If the deceased does leave any children or male grandchildren through a son, the apportioning begins with those with whom the father shares in the fixed shares. They are given their fixed shares. If a sixth or more is left over, the sixth and what is above it is given to the father, and if there is less than a sixth left, the father is given his sixth as a fixed share, (i.e. the other shares are adjusted.)

"The inheritance of a mother from her child, if her son or daughter dies and leaves children or male or female grandchildren through a son, or leaves two or more full or half siblings is a sixth. If the deceased does not leave any children or grandchildren through a son, or two or more siblings, the mother has a whole third except in two cases. One of them is if a man dies and leaves a wife and both parents. The wife has a fourth, the mother a third of what remains, (which is a fourth of the capital). The other is if a wife dies and leaves a husband and both parents. The husband gets half, and the mother a third of what remains, (which is a sixth of the capital). That is because Allah, the Blessed, the Exalted, says in His Book, 'His two parents each have a sixth of what he leaves if he has children. If he does not have children, and his parents inherit from him, his mother has a third. If he has siblings, the mother has a sixth.' (Sura 4 ayat 11). The sunna is that the siblings be two or more."

A man asked the Prophet "What deeds are the best?" The Prophet said: "(1) To perform the (daily compulsory) prayers at their (early) stated fixed times, (2) to be good and dutiful to one's own parents, (3) and to participate in Jihad in Allah's Cause."

The Prophet said, "Every child is born with a true faith of Islam (i.e. to worship none but Allah Alone) and his parents convert him to Judaism or Christianity or Magianism, as an animal delivers a perfect baby animal. Do you find it mutilated?"

Yahya related to me from Malik from Zayd ibn Aslam from A'isha that she used to pray duha with eight rakas, and she would say, "I would never stop doing them even if my parents were to be brought back to life."

The Prophet said, "The biggest of Al-Ka`ba'ir (the great sins) are (1) to join others as partners in worship with Allah, (2) to murder a human being, (3) to be undutiful to one's parents (4) and to make a false statement," or said, "to give a false witness."

Ziyad related to me from Malik from Ibn Shihab that the Messenger of Allah, may Allah bless him and grant him peace, used to go to relieve himself in houses.

Malik said, "Someone doing itikaf should not leave for his parents' funeral or for anything else."

The Prophet was asked about the great sins He said, "They are:-- (1 ) To join others in worship with Allah, (2) To be undutiful to one's parents. (3) To kill a person (which Allah has forbidden to kill) (i.e. to commit the crime of murdering). (4) And to give a false witness."

A man came to the Messenger of Allah (saws) and said: I came to you to take the oath of allegiance to you on emigration, and I left my parents weeping. He (the Prophet) said: Return to them and make them laugh as you made them weep.

He said: There are narrations on this topic from Abu Bakrah, Ayman bin Khuraim, and Ibn 'Umar

Abu 'Eisa said: The Hadith of Anas is a Hasan Sahih Gharib Hadith.

(Once) Abu Bakr offered the `Asr prayer and then went out walking and saw Al-Hasan playing with the boys. He lifted him on to his shoulders and said, " Let my parents be sacrificed for your sake! (You) resemble the Prophet and not `Ali," while `Ali was smiling.

The Prophet. said, "The biggest of the great sins are: To join others in worship with Allah, to be undutiful to one's parents, and to give a false witness." He repeated it thrice, or said, "....a false statement," and kept on repeating that warning till we wished he would stop saying it. (See Hadith No.7, Vol. 8)

(I think that the people of Ziyad informed me that he reported on the authority of the Prophet (saws): A rider should go behind the bier, and those on foot should walk behind it, in front of it, on its right and on its left keeping near it. Prayer should be offered over an abortion and forgiveness and mercy supplicated for its parents.
