`Ali bin Abi Talhah reported from Ibn `Abbas;

﴿قُواْ أَنفُسَكُمْ وَأَهْلِيكُمْ نَاراً﴾

(Protect yourselves and your families against a Fire (Hell)) He said, "Work in the obedience of Allah, avoid disobedience of Allah and order your families to remember Allah, then Allah will save you from the Fire.'' Mujahid also commented on:

﴿قُواْ أَنفُسَكُمْ وَأَهْلِيكُمْ نَاراً﴾

(Protect yourselves and your families against a Fire (Hell)) saying, "Have Taqwa of Allah and order your family to have Taqwa of Him.'' Qatadah said, "He commands obedience to Allah, to not disobey Allah, he orders his family to obey His orders and helps them to act upon His orders. When one sees disobedience, he stops them and forbids them from doing it.'' Similar was said by Ad-Dahhak and Muqatil; "It is an obligation for the Muslim to teach his near family members, and his male and female slaves what Allah has made obligatory for them and what Allah has forbidden for them.'' There is a Hadith that confirms the meaning of this Ayah. Ahmad, Abu Dawud and At-Tirmidhi recorded that Ar-Rabi` bin Sabrah said that his father said that the Messenger of Allah said,

«مُرُوا الصَّبِيَّ بِالصَّلَاةِ إِذَا بَلَغَ سَبْعَ سِنِينَ، فَإِذَا بَلَغَ عَشْرَ سِنِينَ فَاضْرِبُوهُ عَلَيْهَا»

(Order the children to pray when they reach the age of seven and when they reach the age of ten, discipline them for (not performing) it.) This is the narration that Abu Dawud collected; At-Tirmidhi said, "This Hadith is Hasan.''
